Crossfire is running as a default on that card, I know, I have one and we know that it's not necessary to have two HD6950's for this game so its redundant to even consider adding another to run the crossfire. Besides, I read a review, don't ask me where I don't remember, but another HD6950 user complained about it on some other game and when he disabled the default, it ran better. That's my suggestion, I don't have the game yet to really take a better look though.
