True, SETI is still the most popular, but crunching it is not the way to be #1 in BOINC. Believe me, I was crunching SETI even back in the "classic" days, before BOINC even existed, and I have a soft spot for that project. However, I have a hard time throwing any resources at it these days due to the attitude of those running the project.
DNETC is a relatively new project yet. Try typing in SETI and then Milkyway into that Google fight machine. I think you'll be surprised how close the results are.

Shiva, you are correct, of course. The days of CPU crunching are numbered, and now that even a project like SETI will use them, the writing is on the wall. Once the OpenCL standard really takes off, and programmers only have to write one line of code for most GPUs to use...
...the CPU will be just a transfer station of data to and from the GPU. Looks like a few teams figured this out faster than we did. Or, at least they could afford to purchase that power before we could!
