I started out on a 500mhz amd k6-2 where Gandalf did allright, but not spectacular i then moved on to a T-Bird 900 mhz where Gandalf accelerated in strenght and benefitted more from processing power than say Fritz 6 and JR6 i then upgraded my cpu once again to a T-Bird 1.2ghz and along with the improved versions of Gandalf, the strenght increased even more to the point it was as good and better than F6 and JR6 depending on the timecontrols. And my latest cpu upgrade was overclocking my T-Bird 1.2ghz to 1.3 ghz which boast a 300-400 kN/s(in the opening, and middlegame) performance by Gandalf which is about 10 times the speed i got on my amd 500mhz amd k6-2 where Fritz 6 "only" got a speedup of about 5-6 times from 500mhz - 1.3ghz. In the late middlegame and the endgame i get a nodecount of 500-1000 kN/s with Gandalf, which is even more than 10 times the nodecount i get on my amd 500mhz. Now Gandalf running on 1.3ghz it is better than Fritz and Junior at long timecontrols, as good as Fritz in blitz and better than junior in blitz! In conclusion, to get the most out of Gandalf you will have to run it on a fairly fast system, and very important is to let the book.lrn file grow to atleast 500kb before you will see the true strenght of Gandalf, i have read a lot of posts with people complaining that Gandalf was a weak program after 20 games of testing, the book.lrn feature IMO is there to get Gandalf into openings that compliments its playing style and unless the book.lrn file is "experienced" enough to ensure that, you will not see the great play everybody is talking about, on a consistant level.
