after playing call of duty on my bros comp the other day i decided i wanted it

Looking at the requirements for call of duty though it says:
3D Hardware Accelerator Card required: 100% DirectX 9.0b compatible 32MB hardware T&L-capable video card and latest drivers
may seem a silly question but does that mean i have to have a native dx9 card?
both my computers cards are native directx 8. (gf3 ti200, gf4 ti4200)
but it also says: 32MB so it suggests something as low as a gf2mx400 would work..
I'm a bit confused, anyone shed any light on this please
