i just recently upgraded from a gts 250 to a gtx 460 and besides the new features i really dont see a performance increase and im wondering if my cpu is bottlenecking it. i have an amd phenom 2 x2 560 at 3.3ghz on an asus 890gx mainstream board. i dont have any advanced cooling yet i just recently built my system so im not into overclocking dramatically.
460 768 or 1gb?
Noticeable performance while gaming? Where you having problems running a game, or are you talking benchmarks?
