Hi! I did just finish my 2008 hardware -> 2006 chassis build and the machine seems to be running stable. Anyways, I started thinking, this build has the 8800GT card, which requires one 6-pin PCIe power plug. The Logic board has two outputs, and I have a spare mini-plug to 6-pin. I also have an unused Gigabyte 285GTX laying around, bought for a project years ago, but I never used it. I know that the 285 is nothing compared to newer cards, but hey, it's something I already have, and the Mac Pro was later shipped with this card, which gives 70-100% more power than the 8800. And it requires two 6-pins, not 8-pin. I want to keep this Mac as compatible as possible. I've tinkered with hackintoshes before, had great results, but I'm tired of the hacks&cracks. Therefore I was wondering if there is any way at all to make this card act as a stock Mac Pro 285GTX card? Soldering, flashing etc? I don't want a black screen when booting, nVidia drivers that needs to be installed, or switching to the original for a reinstall etc, I'd like to have a fully Mac compatible graphics card. Is this possible, and does anyone have a guide? I have great soldering skills, and no problems flashing the card. I'm probably never going to use this card for anything else than this Mac, but being able to revert back would be a good option, but not necessary.
