So the Nvidia Quadro K6000 was just announced for delivery in late fall / early winter. Coincidentally, that would have been pretty nice timing to have it appear in the new Mac Pro 2013. The 7970 based card that is scheduled to be the "High End" in nMP is slightly inferior to the GK104 series. (Current Quadro K5000/GTX680/GTX770) The K6000 is based on the first fully enabled GK110 GPU. It will be 15-25% faster than anything AMD has to offer in the same time frame. While "better" may equal "faster" it may also equal "more expensive". Lower end Nvidia GPUs for nMP COULD have been GTX760, GTX770, K5000, or even GTX780 (entry level GK110). If you had your choice, which would you have preferred for the "Home Team" GPU? Nvidia, AMD, or Don't Give a Darn?
