Hi Just did some updates on my 5,1 Mac Pro. Upgraded the CPUs with x5680's, dropped 32gig of ram in it(32g more in the mail). Right now I have a ssd boot drive. I am not sure if I really would benefit from a NVME since I edit off of external drives. I dropped the Sapphire RX580 cause what I read so far that is was the easiest option for the buck. I was in a time crunch as well cause of a project I was working on. but now I have time and money from that project to really shop for a card. What would be the best Card for FCPX editing, so far the line up is the 5000 series, VII, and Vegas. Would I even really see enough gains from my RX580 to even bother. I know these cards require the Pixla Mod, is the performance enough to warrant this? I am looking to speed up rendering times while editing, especially with third party plugs like Red Giant, and neat. Thanks!
