Has anyone been using this card? How is it with a CG program like Lightwave 3D? Is it worth it for games? I have a 933MGhz G4 with a Nvidia Gforce4MX card. It's okay but I was wondering if I may get that much more performance with the Radeon card. By the way, has Nvidia abandoned us? They don't sell their newer cards on the aftermarket. WTF?
