Hiya everyone, What Im wondering is this : What graphics card could I use only for Windows that would be supported by my Mac Pro 2006 version, where I can also continue to use my 8800GT for standard OSX usage? My biggest concern being power consumption and getting the power to the card, as I would rather not use a separate power supply. And while the card will not work in OSX, I'd like to be sure the card won't overheat so fan use would still be nice hah. Im looking to do this to squeak another year or two out of my Mac Pro. I realize that I would likely have to buy a switch or manually swap the DVI cables, along with missing the EFI grey screen, which really wouldn't be missed. Thanks everyone!
