They are definitely not cheap at the moment.  An Itanium2 at 900 mhz goes
for about $2,800 bucks on Pricewatch.  That will produce NPS values of >
1.5M for Crafty, for reference (don't think a 900mhz itanium will get blown
off by a 3ghz PIV for example) and possibly higher with some asm tweaking
as has been done by Eugene for the X86 version...
