I've recently been doing a parts list for my first PC i'm building for myself, i've built for friends before, and just saw the new 8400 has come out. its a gaming rig so seems like the best processor of the new bunch but at the moment only Z370 motherboards are available for the 8th gen chipset, do you need a Z370 mobo for boost mode on the chip (getting it from 2.8 GHz to 4 GHz) and if so which of the new motherboards would people recommend, around the $120-$180 price mark, and if not is it worth waiting for the B370/H370 mobo's as i'm not aware of them currently having any sort of release date and i would like to build my PC fairly soon
