I'm currently a CprE @ ISU. My machine is OC'd at 3.2GHz, two cores of which are dedicated towards BOINC projects. I'm also donating a third core and my graphics card to F@H. Any more and it gets too hot :).
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
