Crysis is the game which really set the standard for future games, so if a card can give a Min of 35FPS with 4AA at 1680x1050 then yes that would hold for sometime, and more Devs have licensed CryEngine 2.0 so expect much better games available around this Christmas.
As fas as the Fan Fights go, its Trivial. Unless both the parties have competition they would be eating their belly out and no improvements (People around the net are disappointed with the 280 already), and its good for ATI to bounce back cuz the competition would be fierce and it would be we, the customers who would be reaping the good fruits of that competion.
So guys common lets not fight for a stupid cause as whose got the Bigger one
