for my new rig that i'm going to be building soon i was thinking of either doing the 4870 X2 or 2 4870s in crossfire. i have seen in various games that the crossfire is better to have but by a small margin (5-8FPS)
i was just wondering which would be better for FSX because of the whole no support for dual cards and all but will FSX use the second GPU on the X2?
