X3dFritz is about 6 times faster than an Athlon 1.5 GHz according to Mig. Actually they searched only depth 17 in four minutes. You can verify that, by lookin on the picture in the story you linked to. so If you have an Athlon 1.2 GHz you have to analyze the position about 7.5 minutes to simulate a one minute search on the Quad-Xeon. So 5 minutes for that move would be the same as 37 minutes on your machine. regards Joachim
