I purchased a 3700x with a Asus Prime X470 Pro motherboard, and unfortunately it requires a bios update and it doesnt come with flashback bios so im in a pickle, im thinking of buying a cheap processor like the 200GE to just update it, however it seems that would also require a bios update. Which CPU would work out the box with the X470 that is cheaper than £80 and if it isnt please still state thanks, and any other way i can get around the fact theres no USB Bios update? Thanks.
