FYI quick tip, I noticed crossfire was not working with my 5870s.

I was able to make a copy of TakeOnH.exe and rename it to ArmA2OA.exe, and the next time I ran it crossfire came on and my second video card started being used and improved FPS.

So I'm guessing then next time ATI/AMD puts out the crossfire CAP profiles this will be easy to turn on with crossfire, but for now the rename trick works great.

Crossfire support is being worked by AMD,
there were some issues reported so You need wait for updated profile / driver

How about Nvidia SLI support? I'm running a pretty sweet rig (i7 2600k, dual GTX590's in quad sli and 3 screens in 5760x1200 resolution) but I get very poor performance compared to Arma2 for example.
I have not yet measured the GPU load tho but I get the feeling that SLI isn't working properly. I even tried renaming the .exe but I still had poor performance.
