Well, decided to toss my hat in to the Crunching realm (just started up the other day). Currently working on Einstine and LHC. Nice to support something that is more of a passion than helping to find cures. I'm using my "weaker" rig (an i3-2120 and 580 SC). I do have to say, I like that I can set it to Crunch only during certain times. Comes in handy since it's the 'family' computer.
Looking forward to learning more about this side of DC.
