Evaluating and increasing the performance of a Windows 7 computer. What does the Windows System Performance Index mean?

Index Windows performance determines the configuration capabilities of the computer's hardware and software and displays them as a number called the baseline value. A high base value usually means that the computer will perform better and faster, especially when performing complex tasks that require a lot of resources, than a computer with a lower base value.

Each piece of equipment receives its own sub-value. The base value is determined by the smallest. However, sub-scores show how critical components are performing and help you decide which ones need to be updated.

A computer's overall rating can be used to purchase programs and other software that meet that rating. For example, if the overall computer rating is 3.3, then you can buy any software, designed for this Windows versions, which requires an overall score of 3 or less.

Current Score Range Matters from 1.0 to 9.9. The Windows Experience Index is designed to keep things moving forward. computer technology. As hardware speed and performance improve, the range of estimates will increase. The standards for each index level remain generally the same. However, new tests may be developed that will lower the scores.

To view your computer's base index

1. Open the Performance Tools dialog box.
2. See base value and subvalues Windows Experience Index for your computer. If you recently installed new hardware and want to check if the overall rating has changed, select Repeat assessment. If subgrades and overall grade are not displayed, select Rate this computer.

About the Basic Computer Performance Index

The score reflects minimum system performance based on the capabilities of various components of the computer, including random access memory (RAM), central processing unit (CPU), HDD, overall desktop graphics performance and the ability to play 3D graphics.

Below is general description capabilities of computers with the specified basic values.

Computer performance with an overall score from 1.0 to 2.0 is usually sufficient for most general computing tasks (for example, running office productivity programs and searching the Internet). However, a computer with such an overall rating is generally not powerful enough to work in the Aero environment and to implement additional multimedia capabilities, available on Windows.

Computer with an overall rating of 3.0 can work with Aero and many using Windows 7 at the general level. Some additional Windows 7 features may only work in reduced functionality mode. For example, a computer with an overall score of 3.0 might display Windows theme 7 with a resolution of 1280x1024, but will have difficulty running this theme on multiple monitors. Or can play content digital television, but it is difficult to reproduce high-definition television (HD television).

Computer with an overall score of 4.0 or 5.0 can perform new Windows applications 7 and support the execution of several programs simultaneously.

Computer with an overall score of 6.0 or 7.0 has a fast hard drive and can handle graphics-intensive computing (such as multiplayer gaming, large game graphics, and recording and playback of HDTV content).

If separate program or work Windows systems 7 requires a higher value than your computer's existing base value, you can increase this value by upgrading your hardware. To check if the baseline value has changed after installing new hardware, select Reassessment. To learn more about the hardware on your computer, select View and print details.

Computer index subvalues

Subvalues ​​are the results of testing the capabilities of RAM, CPU, hard drive, overall graphics rendering performance on the desktop and 3D gaming graphics hardware components on the computer. If the overall score is not sufficient to complete specific program or running on Windows, you can use sub-ratings to determine which components need to be updated.

The baseline value is a good indicator of the overall performance of the computer. Using subvalues, you can determine the level of computer performance when performing individual tasks:

• Work productivity Microsoft programs Office. If the computer is used primarily for working with office programs (for example, a word processor, spreadsheets, by email and for browsing the web), then high sub-scores are needed for central processor and memory. For desktop graphics and volumetric graphics, subscores with a value of 2.0 or higher are sufficient.
• Graphics-intensive games and applications. If the computer is used for games and graphics-intensive programs (such as digital video editing programs or realistic first-person games), then high sub-ratings of RAM, desktop graphics, high-volume game graphics, and CPU are needed. A sub-rating of 3.0 or higher is usually sufficient for a hard drive.
• Media center features. If the computer is used as a media center for additional multimedia tasks, such as recording HDTV programs, high sub-ratings of the CPU, hard drive and desktop graphics are required. For memory and large graphics, 3.0 or higher is sufficient.

Why Windows doesn't update hardware ratings

The circumstances listed below may prevent update Windows Experience Index.

• Battery powered. Windows automatically tries to conserve power when using battery power only. So, if a computer is running on battery power, performance ratings will not reflect its true capabilities. Connect your computer to an electrical outlet and start the assessment.
• Lacks free space on disk. The Windows Experience Index tool creates a test file on your hard drive. If there is not enough disk space to create the test file, the evaluation will fail. You can use the Disk Cleanup tool to free up disk space.
• Evaluation is already in progress. If the Windows Experience Index estimator is already running, the scores cannot be updated.
• Display driver is out of date. If the computer uses old version Display driver ratings may not be updated.
• No multimedia support. If your computer doesn't have multimedia support, you won't be able to update your ratings.

Like Windows Vista, Windows 7 OS tailors some of its aspects to the characteristics of the system on which it is installed. For example, the Windows 7 interface changes depending on what graphics hardware installed on the machine: on low-end machines a simple “Classic” interface is installed, and on machines with high-end graphics control units - full version Aero interface.

In addition, by adapting to the hardware, Windows 7 selects some other aspects. For example, for Windows games 7 enables certain capabilities only if the hardware is able to support them. Other hardware-specific capabilities include those related to TV recording (such as how many channels can be recorded simultaneously) and video playback (such as the optimal playback image size and frame rate to avoid dropped frames).

For the inclusion of all these features, not only in Windows 7 itself, but also in third party applications, the program answers Windows System Windows System Assessment Tool, or WinSAT for short. This program runs during the system installation process and whenever other major hardware performance changes are subsequently made to the system. It focuses on the following four aspects of system performance: graphics, RAM, CPU, and storage.

For each of these subsystems, WinSAT maintains a set of metrics stored as a score in XML format. To find out which functionality capable of supporting the computer, Windows 7 only needs to be studied for the latest evaluation. It is important to note that third-party programs may also use some kind of API that allows them to access these scores and therefore provides developers with the ability to customize the functionality of those programs based on WinSAT metrics. A total of five indicators are used, which are described below.

• CPU. This indicator is responsible for how quickly the system can process data, and is measured in the number of calculation operations per second.
• Memory (RAM). This metric measures how quickly the system can move large objects through memory and is measured in memory accesses per second.
• Graphic arts. This indicator is responsible for the computer's ability to launch a combined desktop like the one created by the manager Desktop Window Manager, and is expressed in frames per second.
• Graphics for games. This metric measures a computer's ability to render three-dimensional graphics, especially those used in games, and is expressed in frames per second.
• Main hard drive. This indicator is responsible for how quickly the computer can write and read data from the hard drive, and is calculated in megabytes per second.

In addition to WinSAT, Windows 7 comes with a tool called Score and Improve Computer Performance, which evaluates your system based on information about its processor, RAM, hard drive, regular graphics, and gaming graphics, resulting in an overall Windows Experience Index score. .

To launch the tool, click the Start button, type performance in the search box, and then select Performance Tools and Tools from the list of search results. Then, in the Assess and Improve Your Computer Performance window, click the Reassess button to get an initial assessment. As you can see in the figure, Windows 7 evaluates each of the five subcategories and then produces one overall score.

To get a new estimate (for example, if you change equipment that affects performance), you can click the Retry button again. It is quite difficult to interpret the estimates, but in general the following can be said about them.

• Generally, the higher the score, the better the performance.
• The smallest possible value is 1.0.
• The highest possible value is 7.9 (which is higher than the 5.9 that was maximum value in Windows Vista, reflecting hardware improvements over the past few years).
• The overall score is based on the lowest score. That is, if you receive a score of 5.0 for all other indicators, but a score of 1.0 for at least one, the overall score will still be 1.0.

Studying the Windows Experience Index

Before you go shopping for certain computer components, it would be a good idea to determine which components are needed. Windows 7 OS users are lucky - they have a built-in tool at their disposal that will help determine the performance of various computer subsystems.

Based on this information, you can decide which components need updating. Unfortunately, this feature is no longer available in Windows 8.1, and it was not yet available in Windows XP. However, users of these systems can download applications third party developers, which will help you understand the performance of computer components.

1. Open the Start menu and right click mouse click on Computer.
2. In the menu that appears, select Properties.
3. In the window that opens, in the System section, you will see either the current performance index or a message that it needs to be updated. Click on this link.
4. In the window that opens, click the Update button. The process of measuring the performance of system components will begin. It may take up to several minutes.
5. Once the performance measurement is complete, you will see the test results. Using them, you can determine the “bottlenecks” of the system, that is, those components that need improvement.

One of the indicators that allows you to evaluate the power of a computer and its readiness to cope with certain tasks is the performance index. Let's find out how it is calculated on a PC with Windows 7, where you can see this indicator and other related nuances.

The performance index is a service that is designed to help the user evaluate the hardware characteristics of a particular PC in order to know which software is suitable for it and which it may not be able to handle.

At the same time, many users and software developers are skeptical about the information content of this test. Therefore, it did not become a universal indicator for analyzing the capabilities of the system in relation to certain software, as Microsoft developers hoped for when introducing it. The failure prompted the company to abandon the use of this test's GUI in later Windows versions. Let's take a closer look at the various nuances of using this indicator in Windows 7.

Calculation algorithm

First of all, let’s find out exactly what criteria are used to calculate the performance index. This indicator is calculated by testing various computer components. After this, they are assigned points from 1 before 7,9 . In this case, the overall rating of the system is given according to the lowest score received by its individual component. That is, as you can say, by its weakest link.

• It is generally accepted that a computer with an overall productivity of 1 - 2 points can support general computing processes, surf the Internet, and work with documents.
• Starting from 3 points, the PC can already be guaranteed to support the Aero theme, at least when working with a single monitor, and perform some more complex tasks than the PCs of the first group.
• Beginning with 4 – 5 points computers correctly support almost everything Windows features 7, including the ability to work on multiple monitors in Aero mode, play high-definition video, support most games, perform complex graphic tasks etc.
• On PCs with a higher score 6 points you can play almost any modern resource-intensive game without any problems computer game with three-dimensional graphics. That is, good gaming PCs should have a performance index of no less than 6 points.

A total of five indicators are assessed:

• Regular graphics (2D graphics productivity);
• Game graphics (3D graphics productivity);
• Processor power (number of operations performed per unit of time);
• RAM (number of operations per unit of time);
• Hard drive (data exchange speed from HDD or SSD).

In the screenshot above, the basic computer performance index is 3.3 points. This is due to the fact that the weakest component of the system - the graphics for games - was given a score of 3.3. Another indicator that quite often shows a low rating is the data exchange speed of the hard drive.

Performing productivity monitoring

System productivity monitoring can be done different ways. This can be done using third-party programs, but there are also more popular options for performing this procedure using the built-in tools of the system. You can read all this in more detail in a separate article.

Increased performance index

Now let's see what ways there are to increase the computer performance index.

Real productivity increase

First of all, you can upgrade the hardware of the component with the lowest rating. For example, if you have the lowest graphics rating for desktop or gaming, you can replace your video card with a more powerful one. This will certainly raise the overall performance index. If the lowest rating is for an item "Primary hard drive", then you can replace the HDD with a faster one, etc. In addition, it sometimes allows you to increase disk productivity.

Before replacing a certain component, it is important to understand whether it is necessary for you. If you don't play games on your computer, then it is not very wise to buy a powerful graphics card just to improve the overall performance index of your computer. Increase the power of only those components that are important for the tasks you perform, and do not look at the fact that the overall performance index remains unchanged, since it is calculated on the indicator with the lowest score.

One more effective way To increase your productivity score is to update outdated drivers.

Visual increase in performance index

In addition, there is one tricky way, which, of course, does not objectively increase the productivity of your computer, but allows you to change the value of the displayed rating to whatever you deem necessary. That is, this will be an operation for a purely visual change in the parameter being studied.

1. Browse to the location of the test information file. We talked about how to do this above. Select the most recent file "Formal.Assessment (Recent).WinSAT" and click on it RMB. Go to item "To open with" and select "Notebook" or any other text editor, for example . Latest program, if it is installed on the system, is even preferable.



2. After the contents of the file are opened in a text editor in the block "WinSPR", change the indicators enclosed in the appropriate tags to those that you consider necessary. The main thing to remember is that the result looks realistic, the indicator enclosed in the tag "SystemScore", must be equal to the smallest of the other indicators. Let's use an example to set all indicators equal to the largest value possible in Windows 7 - 7,9 . In this case, you should use a dot rather than a comma as a fractional separator, that is, in our case it will be 7.9 .



3. After editing, do not forget to save the changes made to the file using the tools of the program in which it is opened. After this, you can close the text editor.



4. Now, if you open the computer productivity evaluation window, it will display the data that you entered, and not the actual values.



5. If you again want real indicators to be displayed, then to do this, just run new test in the usual way through GUI or through "Command line".

Although the practical benefits of calculating the performance index are questioned by many experts, nevertheless, if the user pays attention to the indicators specifically needed for his work, and not chase the assessment as a whole, the obtained result can be effectively used.

The evaluation procedure itself can be performed either using built-in OS tools or using third party programs. But the latter seems unnecessary in Windows 7 when it has its own convenient tool for these purposes. Those wishing to receive Additional information can take advantage of testing through "Command line" or open a special report file.

One of the most important criteria that characterizes computer system, is its performance. Let's figure out how to increase this basic figure of a desktop PC or laptop with Windows 7.

Before we get down to the question of how to increase productivity, let's figure out what it is and what, in fact, we are going to improve. In Windows 7 there is such a system indicator as "Performance Index". It is based on an assessment of individual PC components: processor, RAM, graphics, game graphics and hard drive. The overall index is set according to the weakest link. But for a number of reasons this assessment cannot be called unambiguous and many experts are quite critical of it.

Undoubtedly, the power of the above components directly affects the performance of the PC, that is, the volume of processes that the computer can process per unit of time. Next, we will take a closer look at ways to increase the impact of these components to improve the performance of the OS as a whole.

Method 1: Improve Hard Drive Performance

One of the important factors for increasing productivity operating system is hard drive optimization. Many users pay secondary attention to this factor, believing that for the performance of Windows, what is important, first of all, is the amount of RAM and processor power. But in vain, because a slow hard drive slows down the computer as a whole, since other OS components constantly access it to process files and other objects located on it.

First of all, you can clean your hard drive of debris and unnecessary files, which will speed up its work. This can be done both through the system and using third-party specialized programs, such as, for example.

Defragmenting the hard drive helps to increase the speed of the HDD, and therefore the performance of the system as a whole. It can be done using a special system utility or third parties.

In addition, you can increase the performance of the HDD by properly configuring it in "Device Manager".

1. Click "Start" and go to "Control Panel".



2. Go to the section "System and safety".



3. In the block "System" click on the inscription "Device Manager".



4. In the interface that opens "Device Manager" click on the item "Disk devices".



5. A list of physical devices connected to the PC will open. hard drives. This can be one device or several. Produce double click left mouse button ( LMB) by the name of one of them.



6. The hard drive properties window opens. Move to section "Policy".



7. The performance policy is specified here. For hard drives different manufacturers items in this section may vary. But, based on general logic, look for the position that should help increase performance. For example, "Allow caching" or " Optimal performance". After checking this item, click "OK" in the current window.

Method 2: Increasing the amount of RAM

You can also increase system performance by increasing the size of RAM. The most basic and yet effective method to achieve this result is to purchase an additional or larger RAM stick. But unfortunately, this is not always possible, both for financial and technical reasons, because 32-bit Windows 7 supports a RAM size of no more than 4 GB. But there is a way to bypass this limitation.

In order to increase the amount of RAM without changing the hardware configuration, a paging file is created on the hard drive, which forms the so-called virtual memory. When there is a lack of RAM resources, the system turns to this allocated area on the hard drive. Therefore, to increase PC performance, you need to enable specified file, if you have it disabled.

1. Click "Start", and then right-click on the item "Computer". In the menu that opens, select "Properties".



2. The OS properties window will open. On the left side, click "Extra options…".



3. In the shell that opens, click on the button "Options…" in the block "Performance".



4. The performance settings window will open. Here move to the section "Additionally".



5. In the block "Virtual Memory" click the button "Change…".



6. The virtual memory regulation window opens. At the top of it you can check the box next to the parameter "Automatically select..." and the system itself will select the settings for the paging file.

   But we advise you to set the parameters manually. To do this, first of all, uncheck the checkbox "Automatically select...", if it is installed there. Then in the partition selection window, select the one logical drive, where you want to place the swap file. Move the switch below to position "Specify size". After this field "Original size" And "Maximum size" will become active. Put there the same value of the desired amount of virtual memory in megabytes. Then click on the button "Set" And "OK".



7. In order for the entered settings to take effect, you need to restart the computer.

It is important to remember that you should not create a paging file that is too large. Firstly, you thus lose workspace that you could use to store files. Secondly, the access speed of a hard drive is much slower than that of hardware RAM. Therefore, when increasing virtual memory, it is possible to process a larger volume of processes simultaneously, but the performance decreases, which negatively affects the performance of the system as a whole. It is believed that optimal size is a value one and a half times greater than the amount of hardware RAM of a PC. We recommend setting the size of the paging file based on this calculation. If you already have it installed, we recommend changing its size to the optimal one.

Method 3: Disable graphic effects

It's no secret that graphic effects consume a significant portion of the power of the video card and processor and use a considerable amount of RAM. To free up the resources of these objects to perform other tasks and thereby improve overall system performance, you can disable some visual effects.

In addition, you can also optimize the consumption of graphics resources using the video adapter control panel. Installation algorithm required parameters differs depending on the manufacturer and model of the video card, but the essence comes down to choosing between performance and quality, or at least establishing the optimal balance between these two criteria for you.

Timely updating of its drivers and installation of special software designed to optimize the operation of the video card will also help improve the performance of the video adapter.

Method 4: Disable applications in startup

Quite often, during installation, programs are added to autorun, thereby not only slowing down the system boot, but also consuming resources throughout the entire working session. But at the same time, the user does not always need these applications to work, that is, they often consume OS resources in vain. In this case, you need to remove such items from startup.

1. Dial combination Win+R. In the window that opens, enter:

   Apply button click "OK".



2. The system configuration editing window opens. Move to the section.



3. The startup section will open. Further actions depend on whether you want to disable automatic start all elements or just some of them. The first option will bring greater effect, but you need to take into account that there are programs that, to solve your specific problems, it is preferable to leave in autorun. So the decision is yours.



4. In the first case, just click on the button "Disable everything". After this, the checkboxes next to all list items will be removed, then click "Apply" And "OK".

   

   In the second case, uncheck the boxes next to those items that you are going to remove from startup, but do not touch the checkboxes next to the names of programs left in startup. Next, as before, click "Apply" And "OK".



5. After this, a dialog box will open asking you to restart the PC. Close everything active programs and press .



6. After the restart, the selected applications will be removed from startup, which will free up system resources and improve its performance.

Method 5: Disable services

The load on the system is also carried out by various running services. Moreover, not all of them are needed by the user, and the actions of some of these objects have even more negative consequences than positive ones. It is advisable to disable such elements to improve PC performance. The principle of deactivation is approximately the same as the principle of removing programs from startup. But there is one important caveat: disabling services must be treated more carefully, since deactivating an important element can lead to incorrect operation systems.

1. Click "Start" go to "Control Panel".



2. Next, go to "System and safety".



3. Click "Administration".



4. Select from the list that opens "Services".



5. Opens "Service Manager". Highlight the service you want to deactivate, and then on the left side of the window click "Stop".



6. The deactivation procedure will be performed.



7. After that double click LMB by the name of the same service.



8. The service properties window will open. In the dropdown list "Startup type" choose a position "Disabled". Then press the buttons "Apply" And "OK".



9. You will be returned to the main window "Dispatcher", and the service itself will be completely deactivated. This will be evidenced by the lack of status "Works" in column "State" opposite the disabled element, as well as the status "Disabled" in a collumn "Startup type".

After performing the specified manipulations to disable all unnecessary services The speed of the system should increase due to the release of resources. But, we repeat, be very careful about which service you disable. Before performing the procedure, read our separate material, which tells you which services can be disabled without significant negative consequences for the OS.

Method 6: Cleaning the registry

Another way to speed up your PC is by cleaning system registry from outdated and erroneous records. Thus, the system will not access the specified elements, which will increase not only the speed of its operation, but also the correct functioning. For these purposes, special ones are used. One of the most popular applications for performing this task is the one already familiar to us from Method 1 CCleaner.

Method 7: Setting up the power supply

The next option to increase the speed of the OS is correct setting power supply

This method is especially suitable for desktop PCs, as it has virtually no negative consequences. But if you use a laptop, you need to consider whether to use it, as it can significantly increase the rate at which your battery drains.

Method 8: Overclocking the CPU

By default, the processor is not configured to use its capabilities to the maximum. It always has a reserve of power, and therefore there are ways to free up this power to improve OS performance. As a rule, they are carried out using special software. But it is worth remembering that overclocking a processor is a rather dangerous procedure, which, if done incorrectly, can lead to PC failure. In any case, overclocking the processor leads to increased wear and tear, and if done incorrectly, even to failure in the shortest possible time.

As you can see, increasing system performance in Windows 7 is carried out mainly by reducing the load on individual components. In this case, you often need to choose what is more important to you: speed or visual appearance. Although there are also methods where such a dilemma does not arise, for example, cleaning your PC from garbage. In this case, optimization has only a positive nature, provided that you do everything correctly.

Do you want to know which computer component? affects the speed of work more than others, and maybe even slows him down?
This is very easy to do in Windows 7!

Click the icon Computer right-click and select Properties . In the window that opens (in the section System ) we immediately see an assessment of the performance of our computer:

This score quickly helps you understand your computer's performance level (on a scale of 1 to 7.9). And to understand which component and how it affected performance, click the item Performance indexWindows (highlighted in blue).

In the window that opens, we will see a table with a more detailed report and can easily understand which component reduced this rating.

To learn more about this assessment, you can click What do these numbers mean? or Recommendations for improving productivity...

What is the Windows Experience Index?

Productivity Index Windows 7 They call the number of points from 1 to 7.9, determined after measuring the capabilities of the computer's hardware and software configurations. System performance is assessed using the following parameters:

1) Processor (the number of calculations per second is determined);

2) RAM (the number of possible memory access operations per second);

3) Graphics (2D graphics performance for Windows);

4) Graphics for games (3D graphics performance);

5) Main hard drive (data transfer speed from the hard drive).

Basic Performance Index determined by the smallest value. For example, if RAM will receive a score of 3.0 points, and three-dimensional graphics - 1.7, then the base index will be equal to 1.7 points. The higher the base performance index, the better and faster the computer will perform.

Each hardware component receives a separate score. The PC Performance Index's base score is determined by the lowest score in a given sub-score. For example, if an individual component received the lowest score of 2.6 points, the base performance index is also 2.6. The Baseline Performance Index is not the average of the scores, but equal to the smallest.
Individual ratings can provide insight into the performance of the components that matter most to you and help you understand which components need to be upgraded.

Why do we need a performance index?

First of all, in order to maintain computer performance at the proper level, updating those components that receive too low a rating. A baseline performance index can serve as a diagnostic tool for your computer and help you identify hardware components that need improvement. However, you should not rely entirely on it, since it does not show the computer’s ability to operate in extreme situations, such as when the system is overloaded or crashes.

The base performance index should be taken into account when purchasing programs and other software that correspond to the base index of the computer (i.e., in order to find out whether the computer has enough resources to work correctly with any program). For example, if your computer has a base index of 3.3, you can confidently purchase any software designed for that version of Windows that requires a computer with a base index of 3 or lower.

It should also be taken into account that when assessing the performance of computer hardware components, their performance is taken into account separately, without taking into account their joint work. Therefore, special attention should be paid to the compatibility of system components.

View your computer's base index

1. Open the section «. To do this, click the Start button and select the component Control Panel . In the search field, enter , and then select from the list of results Counters and Productivity Tools.

Or Start-Control Panel-System- follow the link “ Counters and Productivity Tools"

Or press the keyboard shortcut "win+pause/break" In the window that appears, follow the link “ Counters and Productivity Tools", which is in the very bottom left corner

Or Control Panel - System and Security - Check Windows Experience Index.

2. View your computer's individual and overall Windows Experience Index scores. If you haven't run a performance assessment yet, there will be a link in the lower right corner "Rate your computer", click on it (if this operation has already been performed, then the link will be called "Repeat assessment".

This process will take some time (depending on the computer), and the screen will blink a couple of times - this is normal, which means the graphics system is being analyzed. While the evaluation process is underway, it is better not to launch any programs at this time. When finished, you will see a window similar to this.

3. If you want to know if the index has changed after a recent hardware upgrade, click Re-evaluate ( or by going to command line, enter the command winsat formal).
If you are prompted to enter or confirm an administrator password, enter the password or provide confirmation.

Let's look at how the Windows Experience Baseline Index ranges and expected computer capabilities:

• 1.0 -2.0 - if the score is within these limits, then you can work on the Internet and office programs without problems:. suitable for most general computing tasks, work in text editors. However, its performance will not be sufficient to use modern multimedia features available in Windows 7 (for example, the computer will not be able to
  support WindowsAero, so after Windows installations will be automatically disabled)
• 3.0 - allows you to use it to perform most modern tasks: working in photo and video editors, using the Aero style in Windows 7 with a screen resolution of 1280 × 1024 pixels. Stuttering may occur under graphical load. For example, when you watch a video or work in a graphics editor.
• 4.0 -5.0 - optimal rating for working with all the features of Windows 7 and the most powerful programs. It is possible to launch several programs simultaneously and broadcast a high-definition TV signal. /
• If your computer is rated 6.0 scores or higher, the high-speed hard drive makes it ideal for highly realistic, high-resolution 3D graphics.

For the most productive work systems, better do not allow differences between the ratings of system hardware components by more than one point. Otherwise, this will reduce the possible performance of the computer due to the fact that the least efficient components will not keep up with the most efficient ones.

Analyzing performance ratings is useful if you want to find out which device is compatible with Windows 7 or the program you are installing, in order to replace this device with a more productive one.

There is a link in the component performance evaluation window Display and Print detailed information about computer performance and system. By clicking on it, you will open a window with detailed information about the device models of your computer. You can print this data and, when purchasing a program, check the capabilities of your computer with the requirements of the purchased program.
