i5 8600k and i7 8700k

[Rockchop]

Are theese cpu's good for mining? And what kind of cryptocurrency can I mine?

[DannHomes]

Of course they're capable for mining. I'm using an i7 7700k for mining Magi coin XMG. But I only could mine after work so about 13hours/day not 24/7 running.

With this cpu you can mine any cryptonight based coin like monero/electroneum, intese coin and so on
or cryptonightlight coins - aeon for example, but do not expect too much returns

Ok, AMD CPU is better for mining, but I need a i5 8600k or a i7 8700k. So, which one i better? Can I mine Monero?

[ferall]

Yes

Whichever has more cores, maybe?

For mining coins which optimized for CPU, it's fine, but i think AMD Ryzen is better since Ryzen offer better multi-core performance while intel 8th gen offer better performance per core. Also, AMD Ryzen have cheaper price with cheap motherboard.

What would be a good AMD motherboard (with many PCIe to GPU mine as well)?

[Rockchop]

Both are 6 cores, but i5 8600k is 6 threads and i7 8700k is 12 threads. Do the threads affect?

[Amstellodamois]

I think I recall it does if every thread has 2 MB of cache.

But please check.
