Maybe your PSU is underrated? I mean, there is the hype of having 500+W PSUs... I don\'t know. OTOH, I\'d suspect something like the AGP subsystem or the graphics drivers (or both). I\'ve got an ATI Rage Fury MAXX, this one has, in retrospect, never been working properly. Almost everything that\'s requiring polygons (be it in OpenGL or Direct3D or even SW mode I think) crashes after a few minutes, PS not being an exception. Linux could be a solution, though. Nvidia... I don\'t know, AFAIK they don\'t give out any docs to write Linux drivers for their stuff which IMO is a reason to not buy their products. I don\'t like binary-only stuff, who knows what it does, especially in kernel mode? No, thanks!
