Hello this may be a dumb question, and I have heard macs do not boot up without a mac graphics card. My question here though is I have a seperate drive bootcamped and I was wondering if I could install a windows card as a secondary card and install the drivers in windows. Then with windows as my target drive use my windows based card. That or start the computer while the drive is targeted in windows with the windows card. Or leave 2 cards in with a monitor on each (windows / mac } after initially installing the drivers for the windows card. I am not even sure if this is a feasible thing. It may just be a stupid idea. Just thinking of cheap ways to upgrade for game playing since I have a 750g boot camped drive also.
