Your first statement sound to me as something near to impossible. Just recently Bas Hamstra said that minimax speed is around 800000 nodes/second. Computer was indicated as Pentium 466M. Usual number of nodes/second that I see on my AMD 400M (for some best chess games like: Crafty, Xchess, Comet...)is around 150000. Even from this I can see that: 800000:150000=5.3 times.
