Turning slightly opptopic now :-) On general computing a 2.8GHz Xeon were approx 1.5times faster than a 1.2GHz G4 powerbook. But with openssl the result were the opposite. The laptop were the fastest machine in the office! This were also the reason why apple always claimed Photoshop were faster on mac than on windows. They found the most intensive plugin using altivec and compared those to windows. The Cell used in PS3 is the next evolution of this technique. Properly tuned it is the fastest stuff on the planet. But it takes time to rewrite old code and learn the proper techniques. Thanks -- MortenB
