In RC5, we're crackin at a rate equivalent to about 1500 Ghz or so. We do about 1.3 M blocks per day, with around 700+/- active members. That equates to about 2 Ghz per active member, though many people are not on 24/7, so there is more potential Mhz available. I would guess we have 2000 Ghz or more crackin' full or part time.
