I have a MSI B450M-PRO M2 mobo, and I recently upgraded to a Ryzen 9 3900X. I flashed my BIOS with no problems and everything is working fine. I have been wondering, though, if I would benefit from upgrading to a X570 board (I'm currently looking at an ASUS TUF Gaming X570 Plus). The ASUS board has two more RAM slots and more PCIe slots, but would that be the only advantage? Any and all opinions are appreciated. Thanks!
