Their hw sucks and= > their software is a joke.. (if you bought Evergreen I'm sorry..) Well, look at my first statement. Until now I believe and believed AMD=20 offered more than others of their 3D specs to the open source community, = to provide support to real open source GPU drivers. Obviously this isn't = true anymore. But why hasn't this been made public? AMD earns a lot of=20 money even from those people like me which remain in the strong=20 believing that they made their contribution to the open source OS communi= ty.
