I play BF3 with everything on high, vsync disabled, and 2x MSAA
I'm having a bit of a rough time. I managed to pick up these two 6870 cards (both powercolor) on the cheap to upgrade from my 5870 (or else I would have picked up a card with more memory). So far it's been a bit of a headache. With the latest drivers (I can't get to 12.4 because it always states I have 12.3 installed no matter what I do) and with the latest caps, my bf3 performance sucks bumbum.
The problem I get is essentially huge framerate drops and choppy performance, even though I only play on high settings (I am aware of the large amount of vram consumed). In fact, a constant occurrence is that the hard drive is constantly being accessed during these slowdowns, and throughout my gameplay, whereas before this just would not have happened.
I already feel kind of foolish for not going to 2gb or waiting for the gtx 670, but now I feel plain stupid. Does anyone have any idea as to what I can do to remedy this horrible performance. Any help you could offer would be appreciated.
Thank you for your time.
PS : I also have a constantly flashing screen in Skyrim, any fixes?

Ditch the stand alone 6870, 6870's were never meant to run more than two at a time. You would need a 69xx or 79xx to run tripple or quad crossfire. If you need more gfx power, upgrade to a current generation high end card.
The dips are horrendous. I was using 11.11 and doing fine with the 6870x2 but when I installed my second card it somehow ended up at 12.3. The dips go down to like 2-3 fps and the hard drive is constantly being accessed throughout, and this is not even on expansion maps (where the vram consumed is higher). Lowering the settings seems to have no effect.
I'd go right back to 11.11 but each time I do my screen's colors get messed up and I have to fiddle with the damn thing for an eternity before I get it to work.
