32-bit means it can only “see” 2^32 (2 to the 32nd power) = 4GB
The computer has to be able to see the (usable)RAM + VRAM + othe
devices on Motherboard, etc
e.g. If you have 1GB VRAM and “other devices” takes up 0.3GB, you wil
only be able to use a max of 2.7GB (4 - 1 - 0.3 = 2.7) RAM
In this case, if you install 3GB RAM, you waste 0.3GB…if you instal
4GB RAM you waste 1.3GB
This one's a bit technical, but it describes some of the nitty-gritt
of 64-bit technology

If this is any indication that 64-bit is the wave of the future an
32-bit will be “obsolete”
*-There appears to be a shift taking place in the PC industry: the mov
from 32-bit to 64-bit PCs.-*-
We've been tracking the change by looking at the percentage of 64-bi
PCs connecting to Windows Update, and have seen a dramatic increase i
recent months. The installed base of 64-bit Windows Vista PCs, as
percentage of all Windows Vista systems, has more than tripled in th
U.S. in the last three months, while worldwide adoption has more tha
doubled during the same period. Another view shows that 20% of ne
Windows Vista PCs in the U.S. connecting to Windows Update in June wer
64-bit PCs, up from just 3% in March. Put more simply, usage of 64-bi
Windows Vista is growing much more rapidly than 32-bit. Based on curren
trends, this growth will accelerate as the retail channel shifts t
supplying a rapidly increasing assortment of 64-bit desktops an
laptops… PC Accelerators built into Windows Vista, such as Window
SuperFetch, improve performance by keeping commonly used programs i
memory, even when the program is closed. More memory capacity on 64-bi
PCs allows SuperFetch to do its job more efficiently

Considering this, SuperFetch is probably the most significant featur
that distinguishes Vista from all other OS's for users of all walks.
Many other features won't be noticeable or even used by the commo
person (that is until commercial developers start using WPF/WFC etc.
and even more DX10). So why not take advantage of it since RAM is s
cheap
Consider that many workers like to have, say 20 windows open and d
not shut down in order to save time in the morning (even Monda
morning), they can now leave 40 windows (or more) open. Also, the mor
RAM they have, the more stuff can be SuperFetched and Auto Dis
Defragmenter and whatever can run more efficiently in the backgroun
when AFK too
For the above scenario, workers will probably “lock” Vista with the S
sleep more because they can resume in 5 seconds anyway…translating to
huge savings on energy consumption
All these are big bonuses from having a large amount of RAM (which i
dirt cheap these days as well as cheaper going forward). Cost
associated with driver/equipment upgrade for 64-bit compatibility may b
more than made up for in productivity savings by having more RAM
This is a huge 32 vs. 64 thread I participated in once in the CNE
community if you want to go through it. There's many links and insight
and heated arguments there.

Some interesting hardcore Vista 64-bit info:-
...all 64-bit versions of Microsoft operating systems currently impose
a 16 TB limit on address space and allow no more than 128 GB of physical
memory due to the impracticality of having 16 TB of RAM. Processes
created on Windows Vista x64 Edition are allotted 8 TB in virtual memory
for user processes and 8 TB for kernel processes to create a virtual
memory of 16 TB.

Some info on a popular title in 64-bit…
Adobe Photoshop® Extended and Acrobat® Pro natively support 64-bit
editions of Windows Vista. Adobe Premiere® Pro, After Effects®,
Soundbooth®, Encore®, and Adobe OnLocation™ are certified on 64-bit
Windows Vista.

Adobe CS4 is 64-bit only on Vista. OSX have to wait for CS5 or
something like that when they catch up.

To put things in perspective, this is what 64-bit does...
*-What are the advantages of 64-bit computing?-*
-In early testing of 64-bit support in Photoshop for Windows®, overall
performance gains ranged from 8% to 12%. Those who work with extremely
large files may realize noticeably greater gains in performance, in some
cases as dramatic as ten times the previous speed. This is because
64-bit applications can address larger amounts of memory and thus result
in less file swapping — one of the biggest factors that can affect data
processing speed.
