Hey guys, So i'm picking up my mac pro 1.2 next week which I managed to score for $150 (X2 2.26GHZ xeon, 8gb ram) Anyway, im hoping to put something like a gtx 660 in it due to its power for money, however the 1.2 doesn't support mountain lion. My theory is this: 1. Leave original video card in, install boot camp win 8 ect.. 2. When install is done, power off and swap to 660 3. Power up on windows 8 side, remove osx partition and assign space to osx hd. either that or il grab a 7950 which is suported by everything, but is $100 dearer. But would that work for me to use?
