CPU Scaling On Nvidia
Using Nvidia cards, the results are slightly different. For the most part, the high resolutions and demanding anti-aliasing put most of the load on the graphics cards. Some differences can be seen when using Battlefield: Bad Company 2, where increasing the CPU performance stops having any effect beyond 3.80 GHz. The older Source engine is a different matter. While AMD performance scales with increased CPU speed, Nvidia only show small increases.
