Yes, this is very simple math. Let a program play against itself on a faster
machine and it will be stronger. The faster program will see everything the
slower does and more.

I'm just not convinced that an 8 processor Fritz will beat Gambit Tiger. Last
year dutch (human) championship has proven that such a Fritz can be killed by
experienced players quite easily. It doesn't stand a change against Kramnik.
