tsukilanh is your Quad OCed? Try a mild OC and see if it improves. salad10203 - nice hijack - 560Ti and a GTX680 are 2 different stories - and is your 9550 OCed.
no its not OC'ed, still stock. I tried the 560ti on my friends computer, he has a I7 2600k and 16gb of ram and ran crysis, my friends gtx470 was running smoother than my 560ti OC.
