So distributed.net brought out a time limited beta openCL client for rc5. For those that have cards like the Raedon 7770 stuff that couldn't run the Stream client, the openCL client works for them. I am seeing a slight reduction in output when using the openCL client instead of the Stream client on the Raedon cards. I haven't tried the openCL client on Nvidia cards. But just thought I'd mention the new client in case there was anyone out there with the 7000 series or above Raedon cards that was just dying to contribute to the RC5 project.
