OS X does NOT support CrossFire or SLI.ibuyufo said:Has anyone managed to crossfire (x-fire?) two radeon 5770 or other radeon cards and not have the desktop lock up?
No.ibuyufo said:MacMan,
I know that OSX does not support it but is it possible to have the cards crossfired and not crash OSX? I dual boot OSX along with windows 7 so it would be nice if I could have both cards in there.

See: http://netkas.org/?p=671
I have 2 x 5770 working perfectly in snow leopard now with quartz 2d/3d and no lockups
Enjoy
