Upgrade of PC to run CoD Properly

[Bikerjack]

My new rig is performing very well. I have tried various settings and AMD CAP profiles. As expected, the Lost Planet 2 profile seems best graphically but the screen does stutter quite a lot when Crossfire is enabled. If I try other profiles (i.e. Space Marine, World of Warcraft) the stuttering is less but sometimes I get green smoke, green gun smoke and ground dust? Is that to do with the various profiles and how they treat colour individually? When I clear the cache it sometimes reverts to normal but not consistently? Any ideas what may be happening?

The good news is that I can now fly on max settings achieving FPS rates of 60 + most of the time. I am using Speedfan to show GPU and CPU temperatures on a separate monitor linked by HDMI and max GPU has been 65 degrees and max CPU 55 degrees - is that acceptable?

The Gigabyte Easytune 6 software wouldn't install successfully - do I need to look into the BIOS at all? I don't know enough about BIOS settings and I am fearful of changing anything without real knowledge.

I have installed the latest 1.07 patch and SMAA.
