My experience is that Gandalf is more than twice faster on PIII800 than pIII450 when other programs like Junior and Fritz are not. The question is if the situation with Nimzo is similiar. There may be also another factor and maybe with the same number of nodes it searches in a different way in fast hardware so I think that the best test is simply to compare the result in test suites. I suggest the follwing test Give Nimzo8 a test suite that it can solve all of the positions but need some time for it and calculate the sum of the times of the solutions. Do the test on different computers and compare the results. Do the same for other programs and you can find which program earns more from fast hardware. Uri
