I am an AE and Editor who needs to replace my current 3.1 8 core Mac Pro.. I mainly use Premiere, Davinci for transcodes and Avid.. so... Late 2015 27" iMac 5K retina 4ghz i7 quad core,32gb ram,500gb flash storage,4gb amd video. It has dual thunderbolt ports and 4 usb-3 ports. better than a 2012 12 core 5.1 with ssd and nvidia video card? i like the fact that i can use thunderbolt..
