Looking at my upgrade history, with typically about doubling of CPU speed at each upgrade - ie; 4MHZ PC to 12MHZ 286, 12MHZ 286 to 66MHZ 486 (more than double there), 66MHZ 486 to 133MHZ Pentium, 133MHZ Pentium to 266MHZ Pentium MMX, 266MHZ Pentium MMX to 450 MHZ Celeron, 450MHZ Celeron to 935MHZ PIII.....the next upgrade will have to be a 1.8GHZ "something" if I want to stay with my established upgrade habits. Looks like a Pentium5 or AMD equivelant in two to three years.
