However, a couple of notes: 1. the G3 is about 2x faster than the P6/200 from my benchmarks. However, I only have G3/275 benchmarks so the /250 is unknown. I'm assuming it scales. 2. Perplexity is not on a pentium pro... it is on a pentium-200, which is at least 30% slower than the PRO... so the speed difference is at least a factor of two. 3. His best ever rating is just over 2500, which leads me to believe that either the machine is used for other things as well, or else he is playing with different openings for whatever reason (IE Brause on ICC plays a couple of *very* specific gambit opening lines 90% of the time.) But in any case, perplexity seems "perplexing".. :) I'll be happy to pop over to fics with my P6/200 if you'd like to schedule a series of games. That way we at least know how my machine performs, what book I'm using and that my machine will be idle except for Crafty... just give me some warning so I can have it jump to FICS...
