I'm interested in this too, Gator-hex, you mean that i can run without problem for example a 5970, 2 5850 and one 6970 in the same rig? I know that if all gpu are from 5000series there aren't any problem, but i don't know if they will run properly mixing with 6000 series... If they work, I should install drivers for one of them and plug the display on it and the rest of cards will automatically run with the same openGL version?
And another question, if I use an AMD apu, can I plug the screen on it and by this way avoid the display driver crash wich sometimes ocurre while I'm using pc at same time as mining?
Would be any problem in using many power supplies for a multi gpu rig instead of one of 1200w??
Thankss!!!
