I'm planning on a building a new system and am torn between ATI's better value but rumors of worse software support (especially for OpenGL) and Nvidia's performance and software support at a higher cost. This system would be used for both windows and linux, and would be used to play games using both directX and OpenGL (and in fact creating games with OpenGL). Any recommendations? Is bad driver support for ATI and opengl old rumors that don't hold water anymore?
