I guess that I know even less about hardware than I thought. I'm surprised that they don't make the cards more backwards compatible. I'll have to do a little studying to see whether I can get a clearer grasp of the issue.
I wondered whether Gigabyte might have a BIOS update to take the motherboard into UEFI compliance, but the latest one listed is from 2009. No mention of that in the short release notes.
Sounds like you may be outa luck in terms of graphics card upgrades. My sympathies.
