To answer your question cfroese.
The i7-970 6 cores get ~92,000 per unit every 1.5 days,
or 62,000 PPD 0n the 6900 bigadv units. Other bigadv
units vary in time and points, from about 80,000 to 110,000
per Work Unit. That is with an overclock to 4.2GHz.
I could do 300k per day if I turned everything on and did not
mind paying $500 per month in electric $'s.
