I am trying to decide if I would like to upgrade my 2010 3.33 Ghz mac pro for a new 2013 model of the same type (aka the 6 core version). My current mac pro has 16GB ram and the 5870 gpu, and generally performs fairly well. I realize there are no hands on benchmarks yet, but I am trying to gauge what sort of % performance increase could be available if I make the upgrade. I primarily edit in FCPX, as well as the adobe creative suite (premiere, after effects, photoshop, etc). I do a bit of gaming as well, but mostly its a bunch of 1080p rendering, and soon to be 4k rendering. I am wondering what sort of benefits I would see from the new mac pro, purely in performance terms. Regarding storage and such, I would just move my internal drives to a thunderbolt raid enclosure, so that doesn't concern me much. What I am more curious about is the % difference between the 2010 6 core processing power, and the 2013 6 core processing power. Also, what is the difference between the dual d500s power, vs either my current 5870 or a card I could instead upgrade to like an nvidia gtx680. Does the fact that the new mac pro is being built with dual d500s mean twice the opencl power, or is the second card exclusively there to power an additional monitor or two? What my question boils down to is, if I were to keep my current mac pro and simply upgrade the GPU to the gtx680 how comparable in performance would that be to a 2013 6 core mac pro? If the 2013 is a solid performance bump, I would instead be willing to sell of my current 2010 mac and go that route. While I know nobody has physically tested the parts yet, any educated guesses based on existing knowledge of the Xeon and GPU equivalents would be very appreciated. Thanks!
