Hi guys,looks like people stop trying to get the new generation graphic card working on mac os in 1s gen mac pro. Is there a way let the graphic card works in windows but stop powering when you switch back to mac os? I'm thinking about to buy a new graphic card when crysis2 coms out, however mac os doesn't look like will work with the card. I have a 7300gt a 8800gt here. I think I can make 7300gt and a new card work in windows, and I would like to shut down the new card when I'm using windows,if I can't get it working... any ideas?
