Using the ASUS utility, I've got the GPU to 440MHz, and the memory to 860MHz. I don't see an increase in fps. Any suggestions as to what I could do? I'm tired of playing Rainbow Six at 22ish fps.
Overclocking a video card is much simpler than overclocking A CPU, Raising the Core clock, Memory clock and giving it a volt modification are the most you can do.
Since games are Very GPU dependent there isn't much you can do with the rest of your hardware in respect to gaining extra performance, Upgrading your video card drivers may give you an extra 2fps, but that would only Impact someone using an older driver version.
All that crap said the best I recommend is to upgrade the card, or to learn to live with it
