I have approximatly 300mhz of 601 processors (1st generation PowerPCs), in a total of 4 machines, they would only turn out approximatly 500kkeys in RC5, I don't normally run OGR, but there is no speed rating for the 601s in the speed calculator. Should I go through the effort of setting these 4 machines up, record speeds, etc. or is it worthless?
