GTX285 is actually 35%+ faster than GTX260 216: http://www.techpowerup.com/reviews/Powercolor/HD_5770_PCS_Plus_Plus/29.html
Any reason you aren't going for 5870? It's faster than the GTX470, runs cooler.
I don't upgrade much so when I do i tend to dig deep for more of future security thing.. like last around 2-4 years?![]()
2-4 years? It's probably better to buy a $180 graphics card and in 2 years get another $180. I say unless the games you play are slow/chopping, then just don't buy for the sake of "future-proofing".
Sometimes its O.K. to stick your neck out and pay big bucks for whats top-of-the-line at the time.
