Hello, I have a MacPro4,1 Quad-Core 2.66 mac with the stock GT 120 video card. Is it possible for me to install a pc card of the ATI, Quadro FX, or GTX 2.. families in my mac and have it work when booting WIN7? I don't care about using it on the mac side but i would like to have it when I boot in windows. Will having that card in my system effect the machine adversely when in the MacOS? Thanks!
