Can you install the 8800 GT graphics card upgrade in these older Mac Pro models? I've currently got an ATI 1900 XT card installed, and I've already had to replace it once due to the card overheating and Apple refuses to actually fix the underlying issue with this particular card. I was hoping I could swap it out with the new 8800 without having to replace my Mac Pro. Is this possible? Has anyone done it?
Thanks.
