The 64 bit version is included with the retail version of Vista Ultimate. If
you buy a lesser version, you can order a DVD from Microsoft as above. I did
that; the charge was a relatively nominal $10. You can use your product key
with either 32 or 64 bit versions (but only one installation should be
activated). It may be legal to get a copy of the 64 bit install disk from a
chum, for use with your product key. (The DVD isn't copy protected; I always
make and use a back-up copy.)
I wouldn't recommend getting Vista Home Basic. It appears to be a stripped
version intended for machines that are too low spec to run the full versions
of Vista properly.
As regards drivers, I waited for Vista until drivers were available for all
of my peripherals.
So far, the only paid upgrade that I was forced to was for Photoshop. CS2
didn't work properly under V. 64. It kept being unable to see the installed
printer drivers (the printer drivers worked in every other application). CS3
works fine. I mostly blame Adobe for choosing to not release a Vista patch
for CS2.
V. 64 also does not permit 16 bit software to run. (Some 32 bit software
uses a 16 bit installer.) That makes Vista unable to run some older
software.
Note that the 64 bit version cannot be installed over a 32 bit OS as an
upgrade.
There may be little point in running 64 bit unless you need to install more
than 4 GB of RAM.
