To be honest, if the R5 can produce the SAME gaming results as the R7 series, but for $260 vs $350 for the i7 7700k, with vastly cheaper motherboards, for the same price you could stick a significantly better GPU in the AMD build...
The Cm Hyper 212 is what i'd consider the absolute bare minimum for cooling a 7700k, it's not really good enough.
Kaby Lake runs HOT, really you should be looking at much higher cooling performance ala Noctua D15 or maybe a decent AIO Water cooler.
No.. the frame time differences on Ryzen are better. Meaning a smoother gameplay.
I've heard it from 3 different recognised youtubers and 2 websites.

Don't look at max fps, look at the min fps.. Ryzen is actually pretty damn good in gaming, and will get better as the bios and drivers mature.
It should be pretty stonking when streaming.
Also many people are reporting that gaming is noticeably smoother on Ryzen.
NZXT are providing AM4 adapters for free.
You will need proof of purchase for Ryzen processor and an AM4 compatible motherboard.
AM4 adapters will ship on or around the 15th.

I agree with Guanyu, you don't need to replace the 4460, especially to a 7600k
If you were to upgrade, you'd upgrade to an i7 or Ryzen, as gaming titles are starting to utilise those extra threads.
Try following this see if it works.
