Not even close. There was a brief discussion here about an IBM system running
dual Power4s for about $15000 which would, judgine from benchmarks, have a
significant advantage over PCs. Another $11000-odd allows you to upgrade it to 8
Power4 CPUs; together with plenty of cache and lots of RAM, this would leave a
PC without chances. Of course, you can keep going if you have money - there are
32-way versions etc... and if you have *real* money, you could start thinking
about supercomputers, but would probably have to develop a "special" chess
engine to take full advantage.
