i5-6600k board suggestions - OC, No sli

[TheGlow]

So far I'm looking at getting an i5-6600k and looking to some mild OC, nothing crazy. I have a 2500k at 4.2GHz currently.
I cant make up my mind on a board. I like Asus, like Pro gaming maybe but not sure if thats overkill. Gigabyte HD3P looks ok but I read it can't necessarily OC that much.
So many decisions. Motherboard is always the roughest for me.
