I have this sapphire x1950 that I wanted to use for gaming. I was pretty certain I could set it up so that when I boot into vista I could use it just fine. With both cards in (stock nvidia 7300 and ati x1950) os x boots fine to normal resolution and what not.. but Vista boots up all ****** with a decreased to 1280 something resolution and wont properly recognize card.. something about the two cards conflicting and can only use that one resolution. I tried to install an update it told me it needed.. when I did so the screen flashed and I was dropped into 4 bit colors.. WTF. Anyway I unplugged power to my x1950 and its back to regular res and color. Does anyone know how I can boot into vista and have it not detect or use my nvidia card but rather just use my ATI radeon? Please help me if you want screen shots or error info I'll try and get it done.
