Hey,
I'm building a new PC soon and I have some questions about picking the right CPU.
I'm mostly playing WoW which is a very single core demanding game, so a good CPU is my priority. Now, I have 2 options:
1)i5 8600k + GTX 1070
2)i7 8700k + GTX 1060
My budget is not that big so I can't afford both i7 and 1070. The question is: which option is better?

Sadly its cheaper to upgrade the CPU over the GPU, so i would take the stronger GPU over the cpu for now.

From the WOW forums

"Here's my i7-8700k @ 5.0ghz:

R15 multi/single: 1665/219
CPUZ: multi/single: 4237/593

Here's the i3-8350k @ 4.9ghz:

R15 multi/single: 822/211
CPUZ: multi/single: 2223/593

I get the feeling WoW will play identically on both of these systems."

As you can see from a single core at almost the same speed the 8700k and 8350k have almost the same score. WOW only uses 1-2 cores maybe 4 cores now that we have Vulkan/DX12 ( havent played WOW in like 6-7 years now) but even at 4 cores the 8600k would have 2 idle cores.

I have the same CPU as the guy in the post you sent and I'm having huge FPS drops in certain situations because the usage of one core is at 100% all the time while the other cores and GPU aren't even on 50%. But yeah, GTX 1060 should definitely be enough for WoW, I'm not sure about other games tho.

From a blizzard rep https://eu.battle.net/forums/en/wow/topic/17616032512

"Thank you for getting in touch with us, and I'm happy to be able to look into this for you. I understand that you're concerned that WoW isn't using all the cores on your CPU, and I'm afraid that this is just the nature of the game. WoW is a CPU intensive program, however due to how the game engine works, the majority of the work is done on a single Processor Core. This is true for a number of reasons, but in general is because most of the in-game calculations are linear, they require the results from previous calculations before being able to run the next operation (think in-game physics, character movement etc.), and this kind of programming isn't suited to multithreaded operations.

This is why you will see one of your CPU Cores capped, while the others are not working much at all, and sadly just due to how the game engine works, and isn't something you can improve through settings.

As my colleague mentioned, Addons can greatly affect performance, particularly if they're actively monitoring your gameplay, such as Damage Metres for example, these can delay new Frame Draws while they process data, so disabling these while you test things can potentially improve your performance."

So having the extra Hyperthreads will not help out in wow at all.
