Does Intel Quad Core & Extreme Processors Support 64 Bit Computing ? - extreme tech deck

I talked about the technical specifications of these processors, where I found that they support Intel 64 architecture, but the overview of the Intel Architecture 64, we read that the processors require additional equipment, support 64-bit.

I have to run Windows Vista Business 64-bit version with or Extreme quad-core or have to go with AMD Phenom?
