Well if you compare Pi2 against desktop GPU then it's not really worth it, but it's boinc so every point counts and Pi2 only uses around 4W. With stock clocks WUs took 24h - 25h 30min and after I overclocked Pi to 1Ghz, WUs took under 21h every time. It was fun to play around with Pi2 and it was my first experience with Linux . Next I need to try OpenELEC and get netflix working somehow.
According to @Whaler_99 F@H client doesn't support the processor in the Pi. Here is list of some Boinc projects and every project that has raspberry icon will support Pi: http://boinc.berkeley.edu/projects.php
So I got Raspberry Pi 2 today. As soon as I got OS working, I downloaded and installed Boinc :3
I prefer pictures over writing so I made imgur album: http://imgur.com/a/WrLq8
Einstein@Home stats for Pi2:
After 3 and half hours, CPU temp has been 63.8 - 64.3°C.
