My job requires the Mac Pro as I do heavy video editing and rendering day in and day out and I much prefer OS X for my work. Just wanted to get that out of the way before someone posts "Just buy a PC then!". I am wondering if it is possible to have a separate graphics card to use only in either Windows 7 or OS X. By that I mean, more specifically, use the Mac 4870 in OS X and use a Superclocked GTX 480 in Windows 7. Instead of buying a separate Windows 7 machine that I can't afford, I'd much rather have them both on one machine and perform the task via Bootcamp. I've been thinking of ways on how to do this by going into the Windows Device Manager and disabling the 4870 and having the GTX 480 be the primary card. The only problem I'm thinking about is how I'll be able to use the same display with two different graphics cards when I switch over. I'm wondering if anyone has any advice on if this can be done successfully and how to approach it. Any feedback is appreciated!
