I have a R7 3800X and I just need to buy a MO. I dont want an x570 as I dont need the features so Im trying to get the GIGABYTE B450 AORUS Elite as its at a good price, has good reviews and has aesthetics I like, but Im worried that I need a Gen 1/Gen 2 CPU to update the bios. Does this MO have Gen 3 ready right out the box? I plan to purchase it from Amazon. Thank you
