Windows Experience Index

Ever wonder how a PC you own—or want to buy—stacks up against others? The Windows Experience Index is one way to find out.

This feature, updated for Windows 7, rates the performance of key hardware components such as the CPU, disk drive, and graphics card. The PC is then given a score between 1.0 and 7.9.

When you are shopping for a new PC, the Windows Experience Index can help you find the floor model that suits your needs. Scoring a PC you already own can help pinpoint slower components worth upgrading. A PC with a score of 2 is typically sufficient for basic computer tasks like word processing or web browsing. Graphics–intensive software frequently requires a 3 or higher.
