Another thing to keep in mind, Vue doesn't really support OpenGL like other programs do. For instance, Maya, Lightwave, 3DS, all use OpenGL to it's fullest with a much higher quality of previews, etc. Vue uses OpenGL to it's advantage, but shouldn't be used as a benchmark of what Vue or OpenGL in and of themselves are really capable of. That being said, I use Vue on a Geforce3 in a Mac and a Radeon 8500 in a Windows XP box, both of which work very well.
