Hi, I have a mac pro late 2010. it has 2 x 5770 with 6 monitors attached. I have put the two crossfire bridges on the gfx cards but in windows when i click crossfire mode in catalyst it just blue screens. I can get infinity running over 3 displays but not all 6 and thats what i want. It wont let you do that unless the two cards are in crossfire. Any ideas ?
