I work with Photoshop, Illustrator, Lightroom and Premiere. How does the multiprocessing (I believe that is the main difference between a Macpro and iMac) affect rendering times? I'm referring to the new Macpro and a new iMac that is supposedly being updated with the Haswell processor. I know that there is no way to compare unreleased machines, however, just based on architecture, how would they compare with render times? Should it be a big difference?
