I have that same card and it has no problem with directx9. I have dual boot with windows xp and windows me and it works fine with games and directx9.0a. The only problem is its 16mb so you can play the newest games out, but thats coz its just an old card, not incompatibilty or stuff like that. Voodo 3 is safe with directx9 as far as i have noticed on my computer.
