GF DDR - HELP! (what drivers to use?)

[Trifecta]

I dont know if anyone else has this problem and I am not sure if the drivers are the issue yet.. however, the new nvidia 6.18 drivers have given me the worst performance ever on UT. I had to reinstall the old 5.33 drivers.

Its an ASUS 32mb DDR PURE
Duron 600
A7V Mobo
128 MB
yada yada

I cant seem to get the board to perform with these drivers...

Any ideas?
