    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.

    Are you talking about a Mac Pro or a MacBook Pro? If it is the first, it should be possible, but maybe MRoogle has an answer.

    I don't see why not, though I imagine that you would need either

    a) Two monitors
    b) Video Switch
    c) A monitor with multiple inputs

    The graphics card isn't used btw until the OS actually starts at some point. So if you were to boot OSX, as long as a supported graphics card is plugged in AND a cable is running from THAT card to the monitor, it will boot up just fine. I think it will ignore the other card. Windows will probably be able to read both cards, so you will have to switch which card is running to the monitor via seperate cable or switch
