I guess my logic was correct after I read the link posted above:
When should you update the BIOS?
"The BIOS should be updated only if the update is needed. For every BIOS update that you are considering, you should first check the list of changes and bugfixes on support.asus.com. If some of those changes solve issues that you have been having (e.g., you've been having problems with loud fans, and the new BIOS corrects the temperature thresholds where the fans kick in), then you should update. If none of the changes are relevant (e.g., microcode for a new CPU has been added to the BIOS, but you're using the older CPU), then you should not update. So, the rule of thumb is: don't fix what ain't broken."
