x64 is better purchased preinstalled on a new computer from a reliable
dealer. That way you get devices with x64 drivers. It is a rock-solid OS.
As to software, this newsgroup and PlanetAMD64 are the most comprehensive
sources for what is compatible and what is not (or must be tweaked).
I took the approach that I was not converting to a new machine, but was
adding a new machine so I still have an XP Pro x86 box for anything not yet
available for x64. Your situation may or may not allow running side by side
machines, but that is the way for me for at least another year.
The prudent approach is that if you have any reservations about using x64,
don't.
