I'm also thinking about upgrading my PC. I have yet a GTX 1070 (great for gaming, but for editing, it's more a CPU thing). Will a i7 6700k be enough for fluid scrubbing h265 4K 100Mbps in Premiere CC ?
GPU acceleration apparently is used to some extent for rendering and playback, when I monitor GPU load I can see it increase whenever I start playing a timeline in the PP program monitor and drop back to zero when I stop playback. I also see some GPU utilization when rendering final output.
Regarding H.265, I have a i7-6700 class machine with a GTX 1070 and I would expect that to be plenty but in my testing there seems to be an issue with the H.265 files out of the
P4P in that PP seems to have difficulty rendering them on the timeline (stuttering and other issues) while other high-bitrate H.265 files play flawlessly. I found some example 80 MB/s UHD H.265 files out of a Samsung NX-1 (link below) and they play like butter in the timeline program monitor, but native H.265 files from the
P4P seem to be troublesome no matter what I do... there seems to be something about them that PP doesn't like. What I am noticing is that if I move the playback head to a certain part in the clip and wait for the processor to settle down then the clip plays smoothly, but obviously it's not practical to do this while editing. But as mentioned other (non-
P4P) H.265 files play without any problem. So bottom line, depending on what the actual problem is with the
P4P H.265 files the issue may not be related simply to processing power, and if a 6700 doesn't work then I doubt the relatively small improvement in a 6700K would matter much (and a dual 8-core Xeon machine is out of my budget.)
What are other peoples' experiences here? What are your machine specs and can you smoothly preview
P4P H.265 files in PP?

P4P H.265 files:
