The hardware is great, but I the UEFI is a bitch on the delux series. Don't know on the gaming series, they have alot of issues with the delux, z170-a series uefis.
I would remmomend MSI or Gigabyte. I personally prefer MSI
Since this gen uses power regulation on the motherboard for overclokcing, I would atleast get
Gigabyte Gaming 5 or MSI M5. If you don't like the color, the krait isn't that bad eaither and is going to be more than a good enough overclocking board. BTW the silicon in the cpu has the most to say
