Yes. However, Intel's 64-bit offering isn't really an "option", but an
entirely new architecture, as different from x86 as any other. There's a
32-bit mode for compatibility, but it might as well be a separate
processor. Nor is this new architecture particularly well-regarded -- it's
hard to program, and neither notably fast nor cheap compared to other
64-bit processors.

AMD's forthcoming 64-bit line, on the other hand, represents a true
extension of the x86 architecture (for better and worse), and is likely to
be fast and cheap. Linux already runs on these, too. Unfortunately, AMD is
holding up release of the "desktop" version while waiting for Microsoft.
