I'm looking to purchase a mini-itx board (specifically, the Asus Z390i) along with a 9900k but there was a review on Newegg that concerned me. The guy said he had to buy an 8 series CPU just to update the bios to be able to support a 9900k. Is this true? Should I be looking for another motherboard because of this? And will I run into this same problem with any other brands?
