E6750@2.66 Ghz overclocked to 3.2 Ghz

4GB DDR2 800Mhz RAM

PNY 8800gts 320mb

GIGABYTE GA-965P-DS3 LGA

Vista64

1680x1050 resolution

Well, for some reason, I totally crap out my videocard when I OC my cpu and just my cpu. I know it's overclocked because I do get better CPU results using Novabench. But when I run games and test my graphics card, it's total crap: unplayable framerates and lower benchmarks. WTF is going on here? I am so sure that the only adustment I'm making is to my 1) CPU FSB and 2) system memory multiplier to keep my RAM at 800 mhz. I have no idea how OCing my CPU could have drastic effects on my videocard. Any ideas? Some crazy voltage issue maybe?

You said you changed the FSB, what did you do to it and you might want to try putting it back to what it origanally was.

Do a ortho test, i'm not sure that is a stable overclock.
