My post applies only to app/projects that require Double Precision. The 4xxx series will crunch single precision just fine. I think a few of the projects have or will have OpenCL apps for ATI/AMD.

IMHO I think the whole DP OpenCL thing is a marketing ploy coupled with corporate ego by AMD. The 4xxx series is pre-AMD and AMD wanted to make its own mark with the 5xxx/6xxx series. Also AMD killed the ATI logo even though that logo had a very strong image/presence in the market. For me this is evidence of the ego theory.
The marketing ploy part is shown in a post on the MW forum from a guy who wrote to AMD asking why no DP in the lower/midrange cards. And this was their response.
