Hi This is my first post here, hopefully i can begin posting a bit more and learn more about my mac pro. I just got a hold of an Apple Graphics Card Upgrade. The part# is MB560Z/A. It's an Nvidia GeForce 8800 GT, but it's the 2006 version with EFI32 firmware (or do i call it BIOS or ROM?) and won't work with the 2008 Mac Pro... and of course my dilemma is i want to use it in my 2008 Mac Pro. So is it possible for me to flash it (which i'm pretty sure it is) and more importantly is it easy to do and could someone tell me how (or point me in the direction of simple instructions) of how to go about doing it? Also, I understand there's always some risk doing these type of things, but would the chance of me screwing up the card be considered minimal? Is it easy to restore to the factory default if i want to place it back in a 2006 mac (i have no plans for that, but it'd be nice to know i have that option). Thanks in advance for any help!
