Core i5-8600K vs Core i7-7700K

[Itz_TryFX]

So I want to buy PC parts on Black Friday/ Cyber Monday and I was wondering which one is better? I know pretty much nothing about the pair of them. Now for the Core i5-8600K some things are higher but for the Core i7-7700K somethings are better. Now since I want to get these on sale I was wondering which is worth more to get please note that the 7th Gen i7 is cheaper than the Core i5-8600K.

I would take the 8600k 11/10 times. 8600k performs the same or even better as the 7700k in most gaming scenarios, and it does multi-tasking, renderring, etc significantly better.

Newer is better since the i5 8600k has 6 cores 6 threads. The i7 7700k only has 4 cores 8 threads. The Mhz is also important and the i7 wins that battle except for the fact that your buying a K processor so your probably going to be overclocking the 8600k anyway so that lead shrinks away. One other thing is that if you go for the i7 7700k then your buying a motherboard and processor that can't be upgraded. The new 8000 chips only work on newer motherboards but will most likely be upgradeable.

When was the last time that intel re-used a socket type (technically they are using the same socket this time around, but isn't backwards compatible)? It seems that every new chip requires a new mobo. I wouldn't count on intel's next chipset to work on z3XX series boards.

Intel's current/recent trend is 2 gens per socket. But you never know until you know.

This is Intel's 3rd generation on the same socket (LGA 1151) which means it's incredibly likely that they'll switch to a new socket by the time Cannon Lake rolls around.

Per 'compatible' socket. 8th-gen is LGA 1151 V2. But yes, you could be right about Cannon Lake (10nm??) on a completely new socket.
