Running amd64 arch on a AMD based chip definitely gives a performance
increase with some things being over 50% faster than using i386 arch.
However, I don't know if anyone has tested Intel's chips in 32/64 mode
on Debian yet. I have heard rumors though that the Intel chips run
slower in 64bit mode than in 32bit mode, but that doesn't make sense to
me unless their chip design was very poor.
