The 1.81 is an AthlonXP 1900+ (1.6GHz), not 1.4GHz. The 1.68GHz Tbird got 1,041,610 nodes/second. 1.81GHz AthlonXP got 1,140,000 (forget the exact number. This ~130Mhz increase only gained just under 100,000 nodes/second. Not sure where you're figuring ~370kn/s going from 1.68 to 1.81.

IMO there is no way.
