Check the official MSI website for details on the B450 Gaming Carbon motherboard.
You'll need the 3600 to refresh the BIOS later. If your motherboard can't handle a CPU-free update, you should stick with it. Alternatively, selling it lets you upgrade to the cheapest AM4 CPU, such as an A6 or Athlon model. To date, no motherboards have released BIOS for Zen 3.
The board features a bios flashback option, allowing updates without using the CPU. You can also sell it if desired.
I’d likely stick with the 3600X for now. MSI confirmed Zen 3 support will be included on their B450 boards via a beta BIOS, but that doesn’t guarantee it’ll be ready at the official launch. Unless you don’t need your setup to function for the next few months.
