should i upgrade my i5 8600k?

[Mahbub]

i have i5 8600k being cooled by Noctua nh u12s on a gigabyte Z370M D3H motherboard and a gtx 1080 amp extreme. is there any use upgrading to I7-9700K? how much difference in games will i see?

don't think the 9700k would give you that much better performance,

In games? Probably not much though just don't bother with a 9700k. 

If you need an upgrade a used 8700k should be a nice one.

No need, overclocked you're already in the top tier of gaming chips, won't see much benefit in those cases. Something you might consider is delidding, which will significantly improve temps and allow for higher clock speeds.

I mean, check your CPU usage in games - if it's constantly pinned at 95-100%, then yes, a 9700K would improve things.

Unless you only play Battlefield 5 which does actually run optimally on 8 cores and up (though even then the i5 is still probably fine, considering you're using a GTX 1080), I doubt you'll notice much of a difference, assuming you've also got a little overclock on that 8600K.

I went from from a 8600K to a 9700K (and now a 9900K). To be honest I didn’t see that big a difference except in CPU intensive games such as Ghost Recon Wildlands, etc. But as others have said I would not upgrade to a 9700k now. If you think the lack of hyperthreading is holding you back, you might want to consider a 8700K. That’s the reason why I upgraded from a 9700K to a 9900K. 
I should add that I was able to get good prices on the used market for my old CPUs so it was worthwhile for me.
