I would like to keep my system running exclusively free software except for the Windows games that I run in Wine. I currently own a Radeon 7970, and it's a great card, but the open source support is terrible. The thing only gets about 1300fps in glxgears. I'm guessing that Nvidia support through Nouveau is better, but I really don't know. I'm pretty new to open source drivers. Any help would be greatly appreciated.
