Would I need to update bios in order for this CPU to work? Or would this z170 board mobo pick it up right away? I bought a 6700k and havent even installed it yet. I figured i might as well pony up the additional 10$ and exchange it for the newer CPU.
if MSI did release support for that mobo for 7th gen CPU's then yes. if you drop the CPU in that board without updating to a version of the BIOS that supports it then it will not boot
