Will a i7 4790 (non k stock) bottleneck a gtx 1080 or ti

[Venom_]

So i currently have an i7 4790 (not k) on a pretty crappy gigabyte board with 16 gb of ddr3 ram and a gtx 1060 6gb. I also have a 144hz monitor and a h55 cooler. Im now thinking of upgrading at christmas to either a i7 7700k which means new board, and ram, and new psu because i may aswell do i complete change as i have a pretty lousy aerocool 600w integrator, or if i should upgrade to a gtx 1080 (probs evga ftw). Dont tell me that i shouldnt get one for 1080p gaming, i might upgrade in the future but to be honest you need at least a 1070 for consistent over 60 fps in say must triple a games, or pubg and destiny. Im using my pc for gaming and also some editing here and there. i have 2 ssds and a hdd and have to put my hdd into my sata 2 ports because my mobo only has 2× sata 3's.
So at 1080p will my cpu bottleneck, and what about higher resolutions. i have looked around and have yet to find a clear answer.

Mechanical HDD's aren't fast enough to benefit from SATA III, except for the cache which allows for small and short bursts of speed with small files that have been recently used.

There will probably be some times while gaming that the 4790 will present a slight CPU limitation with a GTX 1080/Ti at 1080p. But it should be enough to give a respectable gaming experience.

You can either be okay with lowering settings to medium-ish to get higher framerate on your GTX 1060 and go with the new i7-7700K (or 8600K/8700K) and power supply, or you can go with the GTX 1080 (or GTX 1070 Ti) and a new power supply.

*Please confirm you are using 1920x1080 resolution monitor?

If you have Some DDR3 2400 ram in your system it will be within 1-2FPS of a i7 7700K. Otherwise you can see up to a 10-15 FPS dip Low/High when comparing the 4790 to 7700K on lower resolutions like 1080P or 2k. When you get to 4K, the GPU is the bottleneck at that point so your average FPS is about the same. If you are looking just at the average FPS, than you will be within 5FPS @ 2k.

So, i have some 1600mhz ram 2x 8gb
So i will see 10-15 gb dips at 1080p?
and therefore if i upgrade to 2400mhz ram will i get 1-2 fps difference to a 7700k at 1080p?

This all depends on what you consider a dip in performance. Do you really care if you drop from 200 to 120fps? It sounds like a severe drop right? You can just experiment a little. Your 144hz monitor.... does it have g-sync? Have you tried turning v-sync off and using afterburner? Have you tried using fast-sync? All these technologies help reduce tearing (or your experience from dropping if there is a drop in FPS).
Have you experimented with your startup (autoruns from SysInternals can help).
Have you made darn sure there is nothing running in the background (chrome for example is a pig).
This and experimenting with vsync off, etc along with a lower than 144hz setting might make you willing to wait. A 1060 6gb card can easily maintain the 60fps you want in almost any game with the above fiddling. 60fps corresponds to setting your monitor at 60hz.
