After reading and reading and reading about it I still haven't come close to figuring out the candidates for the video cards in the next Mac Pro. If I have to guess, I'd go like this.... Nvidia GeForce 8700 GTS for the lower-end card. ATI's Radeon HD2900 XT for the bto higher-end video card. ATI's FireGL V8600 to take over the Quadro slot. The GeForce 8700 GTS is a very interesting card. It isn't even out yet. It is believe to be a mid-range card between the 8600 and the 8800 GTS. It may come close to the performance of the 8800 GTS. It has an 65nm process which means it will run much cooler than the 8800 series cards. Nobody knows how many shaders it will have. If it has 96 shaders, it will definitely compete with the 8800 GTS. The GeForce 8700 GTS will feature an eight-layer PCB, 512MB of GDDR3 memory, a 256-bit memory bus, and a memory clock speed of 900MHz to 1GHzthat's an effective 1.8GHz to 2GHz. And it will support PCI Express 2.0. The 8700 GTS rumored launch date is November 12th which may coincide nicely with the Mac Pro arrival. I don't know that much about video card drivers. IF the 8700 GTS is one of the video cards in the new Mac Pro and IF there are even more powerful 8700 series cards in the future...can the Mac Pro user use the 8700 GTS driver as the driver for the even more powerful PC type 8700 series cards? There is one more card that is coming out maybe even this month...ATI's Radeon HD2900 Pro. The Radeon HD2900 Pro is said to have 320 shaders working at a yet to be determined clock. The 2900 Pro will have 512 MB of GDDR3 memory and will draw a pretty hefty 150W. Performance should be just under the 320 MB 8800 GTS, but the card will also have a lower price tag. p.s. I have to give credit to Eidorian for pointing me to information on the 8700 GTS and 2900 Pro cards.
