Ok heres the reasoning. The 5850 is going for about 150 to 180 bucks on Ebay (thank you BitCoin idiots) so with that in mind I could in theory get a 6950 2gb for about 50 bucks when its all said and done. On average with the new drivers a 6950 is getting almost 20 FPS more then a 5850. Also a 6950 will be worth more when the 7000 drops thus lowering my cost to transition. So this isnt as much as about performance as it is a money move. The performance boost is just a bonus. 100%? No but my "sources" on the mountain has been pretty accurate lately. My only concern with the 570 is with the new drivers and such the price over the 6950 almost makes the 570 not worth it. I mean they are within 10 FPS of each other now. Is that worth the extra 30 bucks? Not sure still debating it.
