As a user of an ATI 4890, I'd say it should do the trick quite easily... HOWEVER... a year is a year, and depending on the engine BoB is going to use this could change, but personally, for a game that's supposed to be in development for the last 5 years (or more) either of those cards you mentioned should handle it fine. Worst case scenario... plug 2 in SLI or CROSSFIRE mode if a single one can't manage the load OR wait for the game to be release and buy the graphic card that suits you best
