I have direct x 9.0c installed. HL source engine allows the user to select the level of direct x be it 7.0, 8.0, 8.1, or 9.0
If you plan on playing FPS games (first person shooter) especially multiplayer. You will notice lag playing with direct x 9.0 . The V3200 can handle 9.0c but it doesn't do it as well as some other cards.
If you plan on playing WC3, I've played it and it works fine. T43p users seem the think that WOW works well also. Again these are not fps dependant games as are first person shooters.
The V3200 is aging. Did you look into the T60p's? They have the newer FireGL V5200 which is based of the x800 chip. Plus it has twice the vid memory.
And if gaming is your primary reason, I wouldn't go IBM. I'd get an XPS from dell.
