On a serious note, I don't know what your needs, expectations, monitor resolution and system specs are but a 570 should be adequate for another couple of years. Its an excellent card.
I'll be using a 24" Dell UltraSharp; i5 3570k with ASRock Z77 Extreme4 mobo and 8GB of Vengeance low profile RAM. If a 570 can push Max Payne 3 and yet to be released games like BioShock 3 and GTA V, I'll be good.
