I built a 965 build in November, and only recently upgraded to an i7 3930k. I recommend buying the processor one hundred percent. Stable overclocking, and I ran games like Farcry 3, Battlefield, Black Ops, WoW, and really anything else I wanted. It's a great processor.
The great thing about AM3/AM3+ is that when you get more money you can get an 8100 or 8300, and you can keep your same motherboard.
Do it already!
