Title says all. Been waiting for the new Coffee Lake Intel CPUs all summer. I know I will need to upgrade my entire rig (MB/RAM/Cooler/PSU) but I will be keeping my SSDs/HDDs and my GTX 1070. Is it worth the upgrade now or wait a bit (hoping for black friday?)

I mainly be gaming and recording (perhaps slight editing and streaming). Already have 1920x1080 144hz asus monitor.

Will the CPU be bottlenecked by my 1070?

Keep your 4790K and overclock it if you haven't already. The increase in performance as far as gaming goes is marginal at best in most games when upgrading to an 8700K. The Core i7 8700K with its 2 extra cores might net some extra fps in certain games like Crysis 3 or The Witcher 3 but because you don't have a Titan Xp to go with it or a GTX 1080 ti I doubt you'll even see the increase anyway even in the limited scenarios that you would see a difference. Unless you change your monitor I'd keep that PC the same for now. You're only sinking money into something that won't really benefit you as a gamer if you upgrade.

This is very unlikely to go on sale for blackfriday, it is too new. Older 7th gen stuff will likely be the blackfriday fodder.
The 1070 should be plenty for 1080p gaming even 144hz. However you are unlikely to his 144fps unless you reduce your detail levels. See the 8700k review with benchmarks, even with a 1080ti they rarely hit 144fps and I don't recall any of the games sustaining at that level.

There is nothing fast enough to sustain 144fps in all games with decent details. The 1070 is great. Keep it. Just don't expect 144fps like your monitor can do across the board with out significantly cut-down details.

Nothing is guaranteed in future-proofing. Everyone loves the idea of buying something that will be good for"x" number if years. But that promise can't be made. Maybe it will, maybe it won't. The 8700k is a very good cpu. Maybe it will stand the test of time like the 4790k did, maybe it won't. Either way it is a very good cpu today.

The 7700k only offers a modest increase over an OC'd 4790, and, many games saw only 2-3 fps increases even with 8700k. I'd consider the Gtx1080 or Ti to have the better benefit, maybe wait for 10 nm Icelake, but, good luck whichever way you choose, those are difficult decisions sometimes.
