My parents have an Optiplex 760 SSF. They have BIOS Revision A05. It appears the current BIOS is A13! They do not have any issues I know of and I'm just wondering how important it is to update. Also, can I got straight from A05 to A13, or do I have to do each of the revisions in between?
I may be adding a discrete graphics card at some point to help speed things up a bit. I know it is important to update the BIOS before this.
