NVIDIAs GTX 295 CPU Scaling Article
 

The main thing we want to see when we benchmark is that we have a minimum FPS of 30; a few extra FPS is always appreciated, though. What you will find is that with no overclocking you might be able to play a game at high settings, while running at stock speeds and a resolution of 1920 x 1200. But the extra MHz on offer when you move to speeds in excess of 3GHz will allow you the ability to move those settings to very high.
