I don't think it is the graphics card that is holding me up. *even though you need 7800gt or higher for the minimum requirements on COD4*
I think I know what it is, but I'd rather not post it on here incase I'm wrong and I make myself look like a fool in front of you guys *the computing experts, except for wannabe harjuin*
Thanks for the help, and the experience in overclocking. It worked, but didn't make much difference, at least 1-2 fps.
