Hey, I was going to buy a top-spec retina iMac (CAD $3249 + 32GB owc ram = CAD$3700) but then happened to see that I could also get a 6 core mac pro with D500s for a similar price (CAD$3479 + 32gb OWC ram = $3954). I don't need the 5K screen (yet) so would happily buy a 1440 or 1080 with decent colour accuracy for $5-600. All in all, for my needs I'm looking at difference of around CAD$750-800 between the two systems once I'm ready to edit. I'm getting the system for pro video editing (but not pro grading or mo-graph - although I do dabble). I'm looking to be able to edit feature length projects in 4K (h264s, r3ds, dngs - but not necessarily at full rez- -1/2 would be great) with smooth playback in FCPX and premier. I'd like to have a few effects going as well (film convert, re-times, rgb curves etc). This machine is going to be used to cut indie features, commercials, trailers, events and docs. So which system should I get? Will the 6core nMP be worth the extra $800? Thanks for any info/feedback PS have also posted this in the iMac forum. First response I got there was to post this here. Appologies for the duplicate.
