Overclocking
Given the limited nature of the B360 chipset, this will be brief. The MSI B360 GAMING ARCTIC offers a DDR4 boost feature supporting up to 2666 MHz, and that's about it. MSI has a beautiful, well fleshed out BIOS and good in-OS overclocking tools, but B360 is not designed for tweaking. It goes without saying that spending extra money on a "K" variant CPU is a waste on a B360 board.
I will note that I do miss having a Post Code display as I think it is a much more user friendly solution than the Debug LED. Given how good the MSI BIOS is and how few tweaking options there are for this board, I would say this is just nitpicking.
