I know that there is very little difference between all of these CPUs, but which one should I get?
I'm aware of that the i7-9700k doesn't have Hyper-Threading, but it has 8 cores.
Here's my build: https://pcpartpicker.com/list/zs3dQZ
And here is the pricing for the CPUs (In Norway, turned into dollars):
i7-8086k: 545$/617$ (The one for 545$ aren't in stock in Norway)
