A base score of 3 indicates that a computer can run Windows Aero and all but the most advanced Windows Vista features. A base score of 4 or 5 should be able to run all Windows Vista features, as well as play graphically intensive 3D games. At the time Windows Vista was released, com- puters with a base score of 5 were among the best-performing computers available. As technol- ogy improves, the base scores will begin to rise so that eventually computers may need a base score of 10 or 15 to play newer games or run resource-intensive applications.

If an application requires a higher base score than your computer has, it might be time to upgrade your hardware.
