Yeah, I'd definitely invest in a new card. The Radeons aren't really supported. If this is just for 3D, get a FireGL or a QuadroFX card from ATi or nVidia, respectively. If it's for gamingas well, I'd suggest a higher end Radeon if you must have an ATi, or go with at least an nVidia GeForce 7800GTX. Or, try the card enhzflep mentioned, the 9550. I have to believe it is the rest of the power in his PC doing the majority of the work, so it may work for you, too. The software rendering has nothing to do with the gfx card, though.
