I am thinking about building a pc but i really dont know that much about how to pick future proof mother boards, lets say i want to go with a ryzen 7 2700x how do i know if the asus rog strix b450f will work right out of the box?
All b450 and x470 chipset MBs are compatible with 2000 series Ryzen, For 3000 series they need newer BIOS version that may or may not be installed in factory.
For long term Ryzen (4000 series) compatibility b550 and x570 are only ones 100% compatible although they might require newer BIOS version although some B450 and most x470 MBs are said to be able to get compatible BIOS version.
