Please Robert, clear up! Maybe or maybe not. IE for example, using a rough performance estimate for crafty 8 x 900mhz would theoretically like a 7200mhz machine. But in reality, it would run like a (1 + 7*.7*)900 = 5.9 * 900 =5300 mhz roughly using a quad 2.2ghz machine would in theory provide 8800 mhz, but with crafty would be closer to (1+3*.7)*2200 == 3.1*2200 = 6800mhz, which is significantly faster...
