right now im running an 8600GT OC and was wanting a little more oomph from my card. i was thinking of upgrading to an 8800 GTX or a 2900XT, but people keep telling me that the difference would hardly be noticable enough to justify spending that kind of money. if i were to buy a GTX i would want to be able to run games on highest settings for at least another year or two, is that a pretty realistic expectation?
