I agree with the above cpu/mobo suggestions. What monitor are you going to be gaming on? The reason I say that is, the 6850 is a good card but far from extreme. If your going to be using a full hi-def monitor and plan to play new up coming games like BF3, consider going with something with more power. The 6950(that can sometimes be flashed to a 6970) and the GTX 560ti would be the minimum for extreme gaming IMO.
