I have never played with BOINC, but I answered Greg's call for more 16e v5 sievers and brought some resources to bear on NFS@Home. 10 cores isn't much but I figured every little bit helps.
Then I looked up the user Mumps mentioned by Carlos. Wow!

I'm not even a flea on that rhino.
Anyway, I've been bitten by the BOINC bug. In moderation of course.
