Thanks guys. Sometimes it's hard to understand the context of benchmarks.
I had compared the anandtech benchmarks and I found this one as well:http://www.xbitlabs.com/articles/graphics/display/radeon-hd-7870-ghz-edition-hd-7850_6.html#sect3
This one had the 570 holding out pretty well even with AA & AF turned on. Those claims actually made my gts 250 look better
(i get around 30-40fps on ultra and AAx4 and AFx8) than the 7870. This ran counter to anandtechs claims.
Nothings tested in a vacuum so its hard to know.
