What resolution are you playing on? If you're gaming at 1080p, that rig will have a tough time with the newest games (skyrim, crysis 2, BF3, etc.). It doesn't seem like it should, given the amount of dough shelled out for the components, but it's true. You're in a position very similar to mine. I have a Phenom ii X4 955 running at 3.8 GHz @1.4V, which you could easily do too since you've got that nice cooler, and an HD 6870. Overclocking will help you gain maybe 5-8 fps I would guess, and if you can notch the resolution down to 1366x768 if 1080p is your native resolution, you should have a much easier time gaming. 1080p is a big hurdle for us budget gamers. You didn't do anything wrong, that's just the nature of the beast.
