Nvidia has a nice PR. They have a forum for Linux users, and a developper who answers questions, give patches and listen to users and their bug reports. http://www.nvnews.net/vbulletin/forumdisplay.php?s=&forumid=14 I always preferred ATI for their free community support. However their PR is abysmal. Last year they promised to develop drivers for Linux, but they have not updated their buggy drivers since november. Moreover, they do not give specs anymore (above Radeon 9000). They seem to have dropped completely Linux support, since the succes of their cards in the DirectX gamers world. Unfortunately, it seems that it is not only the fault of ATI. They have submitted patches to XFree, that have not been added for more than one year. Some people say that ATI is not very keen to collaborate anymore, but I do not think this is the only reason though. But at least they may open a forum and update their web pages a little more. I think I am going to switch to nvidia next time. I can live with proprietary drivers (temporarily, anyway the graphic cards market evolves so quickly) until there are free and working solutions from ATI.
