I would recommend more ram.
Nowadays games can use more than 256MB..

I have a system with 1.0Ghz Athlon, 512 DDR RAM and a GeForceMX/400 64MB. I still get pretty good framerate in battles with settings at 1024x768res and max effects...about 20fps usually. With all settings at medium I get about 40fps.

Also check your drivers and FSB speed.
Hopefully you're running at 133Mhz FSB...
Make sure you're using the most updated AGP drivers for your motherboard, and I would recommend Detonator 21.83 drivers for your vid card. 23.11 drivers have given me major problems..

BTW, what brand of motherboard are you using?
It actually can make quite a difference.
