I have an iMac and I hate it. I'm thinking about moving to the Mac Pro line or even the z820. I mainly use Adobe apps, mostly Premiere Pro, After Effects, and Photoshop, so CUDA is always good. Do you think that is better off with base 6-core 2013 model or get a 2012 model and upgrade it over time? I like OS X but Apple support is not so great while the HP one is great.
