the onboard SM502 video does not have 3D acceleration. like other PCI-only AOS4 machines, 3D graphics are only available with radeon R100 and R200 cards, as well as voodoo cards. the radeon HD cards are still 2D-only at this point. so if that's an issue for you, you might consider using a radeon 9250 in the SAM's PCI slot for now.
