Well I joined the team. I have multiple projects going because when I started using boinc a few years ago I was like a kid in a candy store with all the places I could put my computing power. Projects such as: Milkyway@home, seti@home, Collatz Conjecture, PrimeGrid, Orbit@Home, Einstein@Home, and last but not least World Community Grid. Those are in order of work performed. World Community Grid is my newest and has the highest resource share of 50%. A lot of those projects I got into when I noticed my gpu wasn't being used often. Most are set to gpu only.
I got started using boinc few years back with my first real computer. An 2.3ghz athalon dual core with a nvidea 9800gt. Then I stopped for a little while. Then I got back into it a bit with my 2500k and my 6950 but also stopped for awhile till now.
My current hardware is a 4.2ghz 2500k, to save heat for 24/7 usage, and a 1000mhz 7970. When I get my watercooling setup finally I will be in excess of 4.5ghz and 1200mhz depending on if all goes to plan.
