AMD 965@ 3.4 ghz
AMD HD 6850
The rest of the specs are the same with the exception of the case.
Also in the starting phase of the game the 6950 reaches 83 FPS and the 6850 reaches 100 and sometimes higher.
I have a 700Watt PSU in both as well, the GPU and CPU both are not overheating at all. Everything appears to have enough power. I have noticed though, that when my framerate drops the GPU usage does not go up, in fact I'll be at 25 FPS and the GPU is only 80% in use and the CPU is doing fine. Chilling at 45C.
Drivers have been clean installed, and are up to date.
