I've got an e4600 @ 3.2Ghz 266x12 at 1.325V. Have 1 8800gt and a second one on the way. 2x2GB OCZ ReaperX pc-8000 Ram, EVGA 750i mobo, Arctic Freezer 7 Pro. Will the cpu bottleneck the system? I live in florida so the ambient temperatures here are pretty high - so either push the cpu more or get the e8400 or leave it the same?
