I flash everything on my computer that can be flashed, I am the type is checks the manufactuer's web site weekly for bios or any driver updates and flash as soon as they are out, yes as was stated earlier sometimes a previous bios is better than the next, but if that is the flash i just flash back to the original, since bios updates, usually fix some known issues with a component, i do recommend flashing, but do have a UPS in case power goes out and please know what you are doing.
