Hey all, I just picked up a couple radeon 5830s, and have them in crossfire on a p7p55d pro. I enable crossfire in CCC, but so far, black ops, cod mw, crysis, and crysis 3 just load a black screen. When I disable crossfire, they all work fine. Tomb raider is the only game I can get working with it enabled, but after running benchmark, I doubt I'm using all the possible power of the cards as I only see a 20 frame jump from my old gts250. I'm running a 550 watt PSU, and am not sure if that is enough power. The PSU calculator seems to think it is, but I have mixed feelings
