After I chose the processor (Ryzen 7 3700X), I wanted to choose the motherboard for my PC. The Asus ROG Strix X470F Gaming seemed pretty good, but I found that the motherboard requires a BIOS update to work with the processor. However, can it be done only with the Ryzen 7 3700X? I can't afford a "secondary" processor to update the BIOS. If I can't do it, can you recommend another good motherboard which is in the $170-$250 price category?
