Wait wait... so you're telling me there will be extremely limited possible upgrades concerning video cards on the mac pro (at least coming from ATI) because of power requirements?
I just don't see it happening. Seeing as the Mac Pro has 300W dedicated to its four PCI slots, but an R600 will take up 250W, maybe it's possible that Apple and ATI will make something happen. But if not, you would have an external power supply, and need some way of getting this power supply into the Mac Pro's PCI bay.
Theoretically it would work, but... And this is assuming the R600 will actually fit in the spot. Considering nVIDIA's old 2 GPUs on-a-chip solution was about a foot long, there is a good chance this thing will be huge.
Then Apple has to provide it. And they will most likely continue to hate gamers, and tell the nVIDIA Quadro thing is what you need for Motion.
Clovertown will be out before the end of the year. That means the probability of a brand new Mac Pro being out before R600 is pretty much equal to 1. So, assuming Apple will bring in support for the new generation of DX10 GPU's (Please may nVIDIA release a GX2 version of their G80, and even better, may the GPU industry take a page out of the CPU industry and start working for performance per watt. What's the point of having a 50W quad core chip next year that will power through anything you throw at it, and two R600's in Crossfire that draw ten times that much?)
Let's start that sentence again...
So, assuming Apple will bring in support for the new generation of DX10 GPU's, which I suppose they must eventually, I think it would come at earliest in the new Mac Pro upgrade that is bound to happen at MWSF2007.
If you want something cheap, I still vote you go for the X1900XT in a few months. If you want something powerful, either go for two, if it is actually possible, or see if you can get a 7950GX2 to work for you.
