NVIDIA has released plans for a new GPU that has the equivalent of 128 1.35 GHZ processors. This processor is designed to carry the burden of processing general purpose applications, so it will be used as a secondary CPU. So if you have the equivalent of over 128 cores in your computer, you will be able to run much more sophisticated tasks, which opens a large window of opportunity for software makers(like Apple). This card, however, will run you a few grand. Will you see it anytime soon in Mac Pros? Probably not. I'd give it a year or two.
