Phil Schiller, sounds like people don't want cards that either suck, don't meet their mid-range criteria, or take a month to ship!
I agree, and hope someone from Apple is reading this.
Right now in the PC world, a "mid range" card is a GeForce 7600GT, 6800GT, Radeon X800XT/X850XT/X1600XT. The X1900XT is a great high-end card , but out of most people's price range. The 7300GT that comes with the Mac Pro is a "budget" card, which would be OK if you could easily upgrade to a midrange card. But you can't.
I think Apple needs to fill that midrange gap in price/performance with one of the mid-level cards I listed above, and make it available. They should have XFX, ASUS, BFG or one of the other big video card manufactureres make them in quantity, since those companies are already cranking out said cards like hotcakes - all Apple needs to do is email them a damned ROM file and we would all be happy.
Pretty much the only way you could get a midrange card in the Mac Pro right now would be to buy a PC Radeon X1600XT, put a 128k ROM chip on it and flash it with a ROM file from the iMac's X1600XT...maybe.
