If a bios update is available at the time,
then read up on the revision and see if anything has been altered that affects you, no point in updating a working bios that isn't going to change anything,
for example, if a revision changes cpu support, unless your changing your chip, theres no real reason to do it,
if it 'addresses stability issues' then it would be worth considering
According to the website there is a new update. Are you saying that it would be pointless to update if the bios was running smoothly?
