For additional $30, you can play Ultra @ 1920 x 1080 with 60 FPS in most games. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130758
But I heard HD 7850 is as good with less power consumption, so if you don't care nVidia or AMD, you can try HD 7850. In this price range, GTX 560 Ti 448 and HD 7850 are the best. I saw a few sale items on GTX 570, but the one in the link actually could beat even GTX 570.
