I Would go for one of these two cards http://www.newegg.com/Product/Product.aspx?Item=N82E16814129230http://www.newegg.com/Product/Product.aspx?Item=N82E16814161426
they are the 2 and 1gb versions of the 7850, and it is a stronger card, it will beat it in every game essentially. Those 560's should be a lot cheaper. Also no matter what you choose 1gb and 2gb versions of cards don't make that much difference right now, and they basically perform the same. But soon a lot of games will eat 2gb ram pretty fast. But I have had no trouble with 1gb ram on my 560ti.
