I'm also curious about expected performance increases for the MacPro.
Alexey, my understanding is that, depending on the PhotoScan algorithms, if the working set fits in the 30Mb L3 and didn’t fit in the current Mac Pro’s 12Mb L3 cache, we're going to see a big improvement in speed. Otherwise, the main speed-up is likely to be closer to the ratio of the speed increase of memory, which has been bumped up from 1333MHz to 1866MHz. Can you confirm?

Hello Holger,
PhotoScan utilizes OpenCL devices during depth maps computation step and several GPUs can be used simultaneously (but not in SLI/CrossFire mode). But as for FirePro cards they should not be very fast in terms of PhotoScan performance.
