seems like a driver problem! What driver did you install ?

Or maybe some hardware problems with the PCI-E Slot

Well you certainly have enough power, and I see no mobo BIOS updates that mention PCI-E or Crossfire..

Try the new card on its' own, and in each slot you're using. Uh, are you using the CAP profile for BF3? I don't really know if performance should be so poor if you are not using it, but I though I'd ask..
