Hi, David.
Nowadays, the software and hardware that won't run on Vista x64 are the
exceptions, rather than the rule. If you mention the specific hardware and
software you are concerned about, someone here will probably recognize it
and say "yes it will" or "no it won't". Until you tell us that, we're just
dealing in generalities and trying to guess which ones worry you.
Yes, some software does have 16-bit components and will not run in Vista
x64. I had to retire my 20-year-old WordPerfect Office Library Calendar for
that reason. But everything else that ran in my WinXP Pro (32-bit) runs
without complaint in Vista x64. During the year-long beta testing, I had
problems with Nero 7 and Adobe Photoshop Elements 4, but those were cleared
up by the time Vista "went gold" nearly a year ago. I now run both of those
without a hassle. Since updating my motherboard last year, I've added a
couple of TV tuner cards (Hauppauge WinTV HVR-1600 and Pinnacle PCTV HD Pro
Stick); those companies have produced drivers so that I can watch TV in
Vista x64's Media Center, but their application software won't run in Vista
x64. I can dual-boot into Vista Ultimate x86 and install the software
there, but I don't want to reboot each time just to be able to use their
applications.
Currently, the Vista x64 does not offer a speed bonus. For now, at least,
Vista x86 is just as fast as Vista x64. I expect that will change, but not
until software developers rewrite their applications to take advantage of
64-bit hardware - and that may be years away.
The decision is yours, of course. But I've been running Vista Ultimate x64
almost exclusively since about November 1, 2006, and I don't expect to
revert to 32-bit.
