As expected, the GeForce 8800 Ultra is 10% faster than the GTX model, mostly corresponding to the frequency increase, but it cost 25% more! It remains to be confirmed, but ATI with its Radeon X2900 XT could take back the leadership for the fastest graphic card on the consumer market. If so, it will illustrate the tough competition between ATI and NVidia for the GPU leadership.
So far, it remains unclear if Apple plans to enhance the choice of graphic cards that could be installed in Mac Pro, if the Radeon 2900 XT will replace the current X1900 XT; or if Mac users will have the choice to install the last models from NVidia. Apple keeps playing this nasty game of using GPUs from the previous generation, mostly for cost reason, making Mac users frustrated over time... without speaking of the lack of support for crossover or SLI on the Mac Pro while the hardware is ready to support both...
