So i built a new system, i have a sabretooth 990fx motherboard, 2 msi raedon7950 crossfired. and a amd fx-820(8 core) and windows 7-64 bit. i have been playing games off steam and every game will lag, skyrim is un-playable, counterstrike go unplayable. this is awful i spent 850+ on this machine. Any help

What about the other card? If there aren't any power cables connected to it (you must connect 2), you should take it out of your PC or you risk damaging it...
