I'm interested in the reviews of the R5 1600 from people on this board. I'm looking to upgrade later this year and that chip seems to be the sweet spot, especially paired with a GTX 1060 for 1080p gaming and general productivity.
I'm running a 1700X, which clock-for-clock, in virtually 100% of games, is functionally exactly the same as a 1600. There's just nothing out there that can remotely make use of threads 13 through 16 yet.
I run that with a 1080 Ti, playing games at 1440@144hz. I've never once run into a CPU 'wall' where the GPU isn't bottleneck. The only time that happens is if you're running a low-graphics e-sports game or playing 1080@144hz+. I'm pretty much always GPU bound at 100-120 FPS in anything I play, although there is often one thread at 95% or higher (but GPU is also running at 100% usage/frequency). CPU runs cold at about 50-55C at all times in normal gaming workloads, because my total utilization has never once gone over 60% (short of synthetics like Prime95, Cinebench, CPU-Z, etc).
With a GTX 1060 running 1080@60 (or even higher refresh, although that wouldn't make sense with that GPU) you'll never run into anything remotely resembling a CPU bottleneck, to the point I doubt you'd ever put any meaningful stress on that CPU with that GPU.
