I bought a Late 2013 Apple Mac Pro 8-core 3.0GHz Turbo Boost up to 3.5GHz, 128 GB RAM, Dual D700 GPUs w/6 GBs of VRAM per GPU. Now the reason I bought this computer is because I work in the Apple echo-system being that I have a Late 2015 15.4" Mac Book Pro Retina, Late 2014 27" iMac, iPhone, iPad, Apple TV ect ect. So I bought this Mac Pro because of the sure speed of the computer and the reliability of it. This is by far the fastest computer I have ever used my scores on the Geek Bench Test were 3880 on the single core and 33,675 on the multi-core score. I shoot pretty much all my video in 4K or even 6K and I'm shooting with 36 and 42 MP cameras that provide a 80 MB RAW file. So I am able to render a 5 min 4K video from my Sony a7s ii in 2:16 and on the Mac Book Pro it took over 10 mins and the iMac took even longer something like 15 mins so step up your video length and you'll really see how much time you'll be able to save.
