Planning on purchasing a 27" 5k iMac for home use only - it will be used for a few work based projects which I may take home occasionally. Footage is shot in 4k to oversample. We used Mac Pros at work which handle the task fine. Editing using FCPX. Also will be using Adobe CC, possibly DaVinci Resolve 12 too. Most of our projects are around 60 mins in duration. The iMac I'm looking at is: 27" 5k i5 3.5Ghz 32GB Ram M290X 2GB 1TB Fusion Will this machine be comfortable doing what I need it to? Is there any major difference between the i5 3.5 and i7 4.0 and between the M290X and M295X when it comes to performance on FCPX/Resolve/Adobe CC? Thanks..
