My desktop is slow etc

can anyone help me.


My system....

I7 860 2600
2x 6970s cards.

What are your motherboard and PSU models?

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

Or maybe some hardware problems with the PCI-E Slot

My system specs.....

Intel Core i7 860 @ 2.60
P7p55d le Motherboard
8gb Ram
HIS Ice q 6970 gfx card
Ati Amd Radeon 6970 card
1000wt Thermaltake Toughpower Modular PSU


Drivers up to date......crossfire enabled

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..
