I'm getting the Ryzen 9 3900X, and I have this whole ROG theme set up so I want the MOBO to match of course. I had my eyes set on a B-450F/E I don't remember, but saw a ton of people saying there were issues with the bios needing to be flashed and what not. I don't care about price so it can even be a maximus or e-atx for all I care. What is the best out of box compatible highest performance ROG MOBO I can get for this cpu? Thanks!
