Why design for obsolete hardware? Within a year or two everybody will be on hardware faster than my quad xeon (which is probably about the speed of a 1.5ghz machine or so). With only so many hours available for working on Crafty, spending time on the parts that new hardware won't fix makes more sense, IMHO.
