My core dueo @ 1.86 w/ 1.5gb of ram does a buildworld -j4 in 24 minutes. 
However, you can't compare buildworlds without looking at src.conf! :)

I would, however, love to see some benchmarks of amd64 vs i386 on the same 
hardware. Quite frankly I wonder if most people would have a use for 64 
bits beyond expanding the limit of time_t, in 2038.
