The specs look great.... for Windows users. That's what the improvements are for. Heck, the Evergreen cards have been out for a year and from the most recent posts and other sources indicate open source drivers aren't an option for them either. The HD 5xxx cards and fglrx drivers aren't a good match either lacking features and complete with bugs. It doesn't matter how great the specs are for Linux users because ATI isn't dedicated to Linux support. They're not investing in it, period.
No announcement yet.
