Should I update BIOS

[pastymuncher]

I always keep mine up to date. Bios bricking the board is very rare these days and if you have bios flashback it isn't a problem even if it did go wrong.

I always left mine as standard (though windows update tends to force the issue these days), quite annoying if you do a CPU upgrade and have to disassemble it at as the new one wasn't recognised though.

The worst scenario is where there is no BIOS that supports both old and current CPU, there were some B350 (or possibly A320) boards that needed a BIOS update to support Zen3, but because they had a very small ROM capacity you had to lose support for Zen if you did that. So e.g. upgrading from 1600 to 5800X3D on those boards could be a faff.
