Hey guys, As a first generation mac pro owner I am anxiously waiting for this card to ship and want it for my system. However reading the forum on www.macrumors.com I found a article and link to www.barefeats.com
http://www.barefeats.com/york2.html stating that the 8800GT will not work in the first Generation mac pro's due to the EFI now being a EFI64 rom and not the EFI32 rom in the older mac pro's. See below.
Quote " ALERT TO OWNERS OF "OLD" MAC PROS! (CORRECTED)
The GeForce 8800 GT is
NOT compatible with the older Mac Pro (August 2006, April 2007) as we assumed. I've been informed that GeForce 8800 GT uses an EFI64 ROM, the old Mac Pros "expect" an EFI32 ROM."
Now I am not completely sold on this and I wait for others who have ordered it directly from apple to try it in their older mac pro's. Has anyone talked to Apple support about this?
I hope barefeats is wrong.
