I'll be editing 4k in either Premiere CC or FCX and Resolve from either a Sony FS700R or Red Epic/Dragon (6k in that case). Any hard data as to what I'm gaining going to 8-cores, if anything? 12 cores is out if the budget, but I'd like to be editing in real time at 4k. I'm a professional photographer as we'll, so heavy Lightroom and PS work. The rest of my config will be D700/1TB/32GB What do you guys think, is there enough gain to justify another $1500??
