If he's doing serious work, then he's probably using OpenCL, and as far as I am aware, the Gallium drivers do not yet fully support OpenCL. When I checked earlier this year, they were getting close, but not yet usable. Has this changed?

Can I finally get rid of the proprietary ATI drivers and still run OpenCL reliably?

"If he's doing serious work, then he's probably using OpenCL"

He doesn't indicate that at all, and I assumed if he were doing "Serious OpenCL work" he'd be using a later-generation card.

5870 has a theoretical peak of 2.7 tflops, a GTX680 has a theoretical peak of 3.1 tflops. even a 7970 has a peak of 3.8 tflops.

you can argue (successfully) that it's much easier to achieve a high proportion of peak on GCN cards, but CL code tuned for a 5870s isn't going to be exactly sluggish.
