Previously participated in @SETI project. Now I have a temporary and not the most successful configuration of Xeon X5570 and 550ti; they can only perform simple work. And BOINC is quite interesting, you feel part of something big and important. By the way now there are even some awards for it. Read about Gridcoin

Thanks for the useful link and for answering my question. I didn't know there is a reward in form of a gridcoin. That's even better, you get rewarded for helping the scientific community. I like the concept and I will definitely look into it more and who knows maybe I will join! Some of the projects they are currently working on are listed on the website. Thanks again.
