I am tempted to buy a classic Mac Pro with a quad core Xeon, 32GB RAM and an SSD instead of the nMBP for both use as a workstation that would run dual 4K monitors and instead of a separate NAS for my 4 6TB WD RED drives, I'd have them all instead the cMP. I was wondering how the performance would be compared to what I have now? a 13 rMBP from 2013? That way I have some baseline on what to expect. I don't do anything too intensive, other than wanting to power 2 4K monitors for writing code and reading papers (LaTex, PDFs, etc)... I don't game and maybe I'll compile the odd program on my computer but anything that requires power goes to the uni's supercomputer. Thanks!
