As still being new to Mac Pro (since 2014, and glad I made the switch from PC), I have an upgraded 2.8 Quad to hex 3.33 single processor (I did the swop myself), and thus have a question for all of you experience fellows. I want to go to 12-core. Being budget minded, I want to get a good, as fast as I can processor for video editing etc. I have found on eBay, trays with 2.66-3.33 12-cores. So to my question. The 2.66 12-core is the most affordable, but will there be any real increase in performance? Currently I have: Genuine 2010 3.33 hex core 24 GB 1333 in slots 1, 2 & 3 (have total of 32 but using triple channel for increase speed) Radeon R9 280X 3 GB flashed PCIe SSD I used the following video editing software Hitfilm VFX Final Cut Pro Logic Pro Any suggestions are appreciated!
