Yep, it does 3D and everything. It's just not very good.
EDIT: Been told that it's not possible to have more than one integrated card. So whilst I have the SiS Mirage 330 integrated into the mainboard, I can't possibly have the Geforce4 MX aswell. Seeing as the AGP and PCI slots are empty, that only leads me to believe that there's nothing there, other than the integrated Mirage. Which doesn't make sense because there is no way that the guy who gave this to me could possibly run TES: Oblivion on an integrated 32mb card. Hell, I used to play Oblivion at his house on this thing from time to time, and it ran fine.
