Question about Intel Core i5-8600K

ps: michiizyset: please inform yourself properly for the ninth time before you spout such rubbish

Thank you for this kind and helpful answer.

Basically yes.
The z170 chip is a little weaker in comparison with a 270 chip, but in my opinion it is not really noticeable.
Keep in mind, however, that you must not save on the other components. It won't do you any good if you have a fast CPU and a suitable motherboard and then install weak RAMs ;)
