Imo, wait about a month before buying. They are already starting to liquidate 4xxx cards, and there's going to be some great deals coming up. 4870s (512mb) were on sale for $113 AR recently, and that's bound to go even lower with the introduction of DX11 cards. You'll be in a better position to decide what's best for you at that time.
