I have a 570 and it performs absolutely fine, I play Battlefield, Crysis 2 and Skyrim on it and I have modified ini config on skyrim for better quality and I still run it fine and I have a super bad CPU aswell lol here is the GTX 570 (factory overclocked) on battlefield 3, but to the guy that compared a OC'd GPU to a reference is a bit unfair, I think that you should calculate the percent overclocked and overclock them both and then compare, it's like me saying that my 570 Classified OC'd has better performance than a 7870. I know that it has a better overclocking capability but I don't like overclocking my graphics card, so calculating the percent difference is a better test.
