<strong opinion=ON> It still isn't AMD, so it still ain't x86-64. Intel calls it IA-64 aka EM64T for a reason, it's not the full x86-64 ISA. So as far as I'm concerned, you're really no better off on a server whether you run i386 or x86-64 on EM64T -- especially for anything I/O intensive. </strong opinion>
I thought IA64 was Itanium only?
