Hey guys, thinking about replacing my Retina 2012 Macbook Pro with an iMac. I have a couple of questions. The minimum configuration I would get would be the 2 TB Fusion drive one. At heaviest, I do Photo editing and light (we are talking iMovie) video editing. Would last years 5K iMac be good enough (I have no problem buying through the refurb store. I am not that artsy that I would notice the difference in color gamut). Also, I have been thinking, the 512 GB configuration would be outside my budget but I am thinking about the 256 GB SSD, I already keep photos on external storage, so I thought that the 256 GB SSD and like a 2 TB USB3.0 Hard drive would be a better way to go. Though it would be convenient to store everything in one place. Lastly, I work from home one day per week. I have a set up with a rain stand and an external monitor. Currently I have to just switch out laptops, to my work PC. Would I be better off with the 4k 21.5 or just switch things around one day per week? I do love that 27" screen.
