Depends what you get
You get a processor with a price that makes sense to be 64-bit, it will almost certainly be 64-bit
All Xeons less than a year old will be, all Pentiums 4 Prescotts... some Northwoods... Gallatin, some other ones. All 5xxs and 6xxs. Most people thought won't buy second hand ones! So all the Processors they buy as Pentium, Xeon or Itanium, will be 64-bit.
By merely using nowadays on the Intel bit, you could have cancelled that out, because you can say the same of Intel. You won't buy a new up to date Intel Processor without 64-bit unless its a Celeron D.
