I want to run windows 7 and osx lion. Each will be on its own hdd. I want it to be a good gaming computer, and because the best hackint0sh gpu is nvidia gtx260(old and not good enough), i am wondering if i can get 2 gpu(s) and have one of them be good, and one be bad. I want my windows to use to good one and lion to use the bad one. The mother board i'm looking at has "two way graphics"(Gigabyte LGA1366/ Intel X58 SATA3 ATI CrossFireX ATX Motherboard GA-X58A-UD5) can you please help me with this problem. I really want a hackint0sh, however i want a good gaming computer more. I have not built the computer yet, but i just want to know if this is possible to do.
