(i5 8600k or i7 8700) + gtx 1080?

[xlonewolfx456]

Hey folks,

Is this build good?
i7 8700
asus z370-e
gtx 1080 mini
16gb ddr4 ~2666
samsung 850 evo 500gb ssd
600w psu

I'm confused if I should go for i5 8600k (I've seen bechmarks and know that, when OC'd, it beats i7 8700).
In my country i7 8700k (including 212 evo) costs 40% more than i7 8700 and i5 8600k (including 212 evo) costs equal to i7 8700.

Also, factoring the climatic conditions in India during summer - I feel OC'ing on air wouldn't be amusing.

I'll be gaming at 2560x1080 (ultra wide 21:9) @75fps. I understand this build is kinda overkill at this point of time but I'm looking for future proofing say for 3-5 years atleast.

Another question is:
I understand how turbo boost works for coffee lake but I've heard there are stability issues with it.

Seems like I'll require an after market cooler (again 212 evo should be good for turbo boost) to harness turbo speeds.
I want to know if anyone else has encountered stability issues with turbo boost - be it high temps, power, etc.
Also, is there an option on mobos to limit turbo boost speed to a somewhat lower number? say 4ghz on all cores? this way I can save power and keep CPU healthy.

Thanks!

P.S: Yes I've seen other threads on this but they don't answer my questions. Especially on turbo boost factor of i7 8700.

The Z370 mother boards do have stability issues right now that needs to be addressed.
