Well, it will be OK, but you can build a better system that will get 25%-50% better FPS for the same price/cheaper. If you don't want to go that route, get a Phenom/i3 barebones. What's your budget anyway?
My budget is at most 500 dollars and 200 of that is taken out due to the gtx 560non ti. And if you have any other barebone kits that are better that the one I have posted please now show me.
