I was going to buy an MSI Z270 TOMAHAWK ARCTIC motherboard, thing is I read somewhere that z270 motherboards need a bios update to accept the 7700k ??? is this true, as i thought it was made for kaby-lake any advice would be great, thanks guys
No, Z170 needs an update to run KabyLake. Z270 is fine for both Sky/KabyLake. If in doubt, go to MSI's webpage and check CPU compatibility.
