TheInquirer reports that GeForce 8900 GTX has more shaders and this will speed up some of the games and definitely in the "scientific" GPGPU calculations. The card still has the same G80, 90nm core but NVIDIA might be veiling some info. The card will be announced just in time to spoil the ATI's fun with R600 launch.

If Geforce 8900 turns out to be using the G80 chip, that will mean that the chip had more Shaders all along. Our sources confirm that Geforce 8900 GTX has more shaders. We know that this will speed up some of the games and definitely in the "scientific" GPGPU calculations. We heard that the card still has the same G80, 90 nanometre core but Nvidia might be veiling some info. We know you cannot clock the G80 more than 630MHz unless you "goto" water cooling. With that you are still topped at 680+MHz.
