StarCraft II Revisited: How Much Gaming PC Do You Need?
By

StarCraft II is very attractive at its Medium graphics quality setting, yet it is a lot easier on the hardware than the Ultra quality setting. Therefore, we’re testing the same Medium and Ultra quality settings that we used in our previous StarCraft II beta performance analysis.

The AMD Catalyst 10.7 beta drivers (and newer 10.8 package) allow us to test AA on Radeon cards. Nvidia's drivers have supported this capability from launch day. However, we limit AA tests to the graphics cards that can supply playable frame rates at Ultra quality settings.

While some of the Gigabyte graphics cards employ a factory overclock, we're setting all of the cards to their reference clock speeds in order to provide a more useful comparison for the folks gauging standard performance.
