OpenGL Gaming: Doom3, Warhammer 40K
All systems perform essentially the same in Doom 3 with the exception of the nForce 4 SLI board (in non-SLI mode). Like 3DMark 05 on the previous page, performance does not appear to be affected by the change in CPUs.
The ASRock K8 Combo-Z does not perform very well in Warhammer 40K. Regardless of the CPU used, it performs the worst of all the systems.
