You will most probably be able to get the HD5870 for R4000 at rAge, so if you want one then that is the place.
In general the performance is what I expected from AMD. I am hesitant to publish benchies using the beta drivers, would rather wait a bit for at least some driver maturity, it just seems like a better approach to me. The HD 5870 is about as fast as the HD4870X2, and maybe a little slower than the GTX295. I am hoping that improved drivers will nudge it up slightly.
