^ care to explain that? If you ask me, only the 7700k and 8700k are proper 144hz cpu. And gpu wise a 1070 for 1080p and 1080 for 2k and likewise. U need both a proper cpu and gpu for 144hz, gsync or freesync can mitigate that a bit.
For 1080p gaming, the gpu will become the bottleneck way before the cpu. My R7 1700x @3.925mhz on my 1080Ti can eaily push 144fps@1080p. But its my opinion over yours. Personally I'm running 1440p/4k @ 60fps. Keeps my card cooler. I prefer visual detail FPS.
Price wise the 8700k in the UK is about £80 more, plus more for an appropriate mobo. So about £100 - £120 more for cpu and mobo combo. For £120, you can go from a 1060 to a 1070, or even a 1070 to a 1080. Upgrading gpu will make more of a difference.
I agree - GTX1070 minimum for 1080p high/ultra settings.
