What specifically do you DO with the PC?
The 8700k unquestionably has more multithreaded power, but would you USE that power?
I'm gonna be pretty much running some codes as soon as I enter university, but other than that, mostly gaming. The thing is that I've noticed people saying that the 8700k is gonna be future-proof since more and more games will be optimised for multi-threaded oriented CPUs. There is also the fact that my CPU which is running @ 4.2 Hz is on 100% usage causing fps stutters and drops whenever I play games like BF4/BF1/ARMA-3 while my GPU is pretty much asleep. Could it be completely the CPU's fault or does it have to with the fact that my monitor is only 1080p, thus making my CPU take all the load while the GPU doesn't give a damn?
The 8700k - or even the i5-8400/8600k - would indeed be more future-proof, but it also means a motherboard replacement too.
BF1 is definitely a CPU hog; I'm surprised at ARMA. ARMA beats the crap out of one core and that's about it.
To sum it up, the 7700k would offer a definite improvement over what you've got now, but a 6-core Coffee Lake (be it the i5 or the i7) will offer even more power in reserve if/when you need it.,,at the cost of the CPU AND motherboard. H-series motherboards will be out early 2018; Z-series are out now. The CPUs are still a bit scarce and hard-to-find though.
