what's the difference between 32 and 64 bit vista ultimate? should i and can
i upgrade from 32 bit vista home permium to 64 bit vista ultimate?
 
In general, most home users do not need to run a 64-bit version of Windows,
and will find it difficult to get drivers and software that are compatible
with 64-bit Windows. There are a few rare cases where a home user will need
to run 64-bit Windows instead of 32-bit Windows and in those cases they will
know they need to.

The big difference really is the power, 64 bit is more power. Vista x64
supports up to 128 GBs of Physical Ram, with 16 TBs of virtual memory. 32
Bit Vista supports only 4 GBs of RAM because of the limitation the 32 bit
architecture which has been around for the past 20 years. No you cannot do
an upgrade of Vista x64 from 32 Bit versions of Windows. It also requires
that you have a 64 bit capable processor and 64 bit device drivers for all
your devices. Applications that are 16 bit or 32 bit apps with 16 bit
installers will not work. Its hard to see the immediate value right now for
consumers since a lot of mainstream applications still do not take advantage
of features of the architecture such as the large memory space and most
systems today ship with 1 to 2 GBs unless you request a machine with 4 GBs
which 32 bit Vista can already handle.

First and foremost: if you're running 32-bit hardware, you CANNOT run
64-bit software, such as 64-bit Vista. Second, before you try to go
this route, you should make certain that 64-bit Vista drivers exist
for your peripherals. Not all manufacturers have gotten to that point
yet.
 
hey guys thank you for your responce. they were very helpful. in my days 8
bit register was a micro, 16 bit register was a mini, 32 bit register and up
was main frame. the size of the register was a consideration when writing
system software but not so much in developing application software. you are
right the drivers would be an issue and applications with sub-routines
(objects) written in assembly would not work. A few mili seconds faster or
slower is not an issue for me :)
 
"...will find it difficult to get drivers ... that are compatible with
64-bit Windows."

This is often repeated here but never backed up. It has not been my
experience. With the exception of a few old Canon printers, if there is
a Vista driver, it's available for 64-bit as well as 32-bit. So it would
be nice if anyone who makes the statement gives one (new) example.

"will find it difficult to get... software ... compatible with 64-bit
Windows"

Apart from pseudo driver software and old 16-bit stuff, software that's
compatible with 32-bit Vista is also compatible with 64-bit Vista.
