I appreciate the reply, but your build will have lower performance than mine! I already have an aftermarket fan for my AMD so it doesn't get too hot (I plan on OCing to about 4.6 Ghz). The i3 2120 is a nice processor, but its locked and that is a real deal killer for me. The 7850 will not run BF3 on Ultra at 1920x1080, the 7950 will. The reason I went with a 750W PSU is because A. I am OCing, and B. I am considering running a dual GPU set up in the future. Also, the farther you stay away from maxing your PSU the longer it tends to last.
Sorry, I should've been more clear! That build I listed is what I am thinking of getting, total is around 850 (budgetish IMO). I already have an OS and some optical drives lying around. I am a tad worried about my mobo and OCing, but I do really appreciate the price I can get on it at micro center. A 990 mobo would be 20 bucks more, is that worth it?
