i had an new 3xxx series AGP card in my former desktop, and it caused me nothing but hassles even with newer games. Drivers would randomly corrupt, i would reinstall and all would be good....for the time. Random blue screens and constant artifacting and color-errors are a small sample of what the card gave me.
The cards are actually PCI-e cards, but there is some sort of pass-through that allows them to function on AGP systems...kinda. It seemed every time i upgraded my hot fix drivers, the card would become even more unstable and i ended up using the ANCIENT ATI Omega drivers, since they offered the most stability for my setup.
I was also able to play FF7 just fine with my ATI card, along with Aali's driver. I'd give the old Omega drivers a shot. The hotfix drivers are just hacks of real drivers that ATI puts out so 3rd party users have something to try.
I am still a fan of ATI though, just not those particular half-breed cards. It was poor implementation and even poorly supported. If nothing else, hop on ebay and grab the last HIS NVIDIA card that was produced. Its a solid card for being al old as it is, and if your rocking AGP still you can't really complain. The bus is wayyyyy outdated at this point, and your almost better putting your money towards an entirely new computer.
