C2D 6600 @ 2.7 (poor i know, but havent reset my settings after a HD failure months ago while i had no internet access) - running F@H console on both cores and getting rough 6-700 PPD (though very unit dependent - Gromac 206 units bring it right down)
EDIT - probably up on average 10 hours a day, but strongly depends what i`m doing that day
