For gamers it would be certainly a nice update, especially when you want to use tesselation - like the Unigine Heaven benchmark (and maybe the OilRush game, no idea about id tech 5). You should not consider a GTX 470 or 480 anymore. Better a GTX 570 which needs less power and is about as fast as a GTX 480. Instead of a GTX 460 the GTX 560 is also more powerful. Forget the GTX 4 series if you have got enough money. GTX 460 is only good when you can not afford a GTX 560.
