Is there a way to install a PC version Nvidia Quadro FX4500 PCI-E in a G5? I tried installing it in a G5, hooked up the power cable, but don't get a video display. Can I just load a Mac driver for this card, and if so where can I find one (Nvidia doesn't support Mac, even though Mac sold G5s with them in it, and Apple won't sell me just the card). Is it that they use a different bios configuration? Any help would be deeply appreciated. Thanks.
