My finances are limited, so one >of my options is to choose between a fast Pentium 3 and a slow Pentium 4.^ A Pentium 4 achieves about 70% of the performance of a P3 or Athlon with same MHz. So the speed of a Pentium 4 with 3 GHz is equivalent to the speed of a P3 or Athlon XP at 2.1 Ghz (Athlon 2600+). For chess Athlon is still the king of the hill and much cheaper. Since a year the heat problems have also gone. So buy an AMD or better wait a few months and by an Athlon 64 (which is according to some posts a real beast for chess). regards Joachim
