No. Unlike common misconceptions 32bit applications and 32bit games do
_not_ benefit from x64 Windows. All 32bit applications are limited to 2GB
(or 3GB depending on the application) of memory. This is also the case
with Vista x64.

Small clarification: on x64 editions of Windows, LARGEADDRESSAWARE 32-bit
applications actually have access to 4 GB of memory space instead of the 3GB
limit on Windows XP booted in /3gb mode.

IMHO the x64 inly makes sense if your computer has more than 4GB of memory
and if you have 64bit application to run. If not stay with the 32bit
version. Less hazzle and problems...

Once you expect a single application to use more than 2 GB of physical RAM,
x64 editions make sense. You can probably utilize 3-4 GB with multiple
memory-intensive things running at once, but to get utilization out of 4 GB+
of physical RAM you really need to be running an x64 OS and memory-intensive
appliations that are either 32-bit LARGEADDRESSAWARE or 64-bit native.

How quickly developers will regularly provide x64 aware versions of their
games really depends on how many users choose x64 editions. Right now,
traditional memory-hungry applications (CAD, video editing, etc.) are
pushing x64 native versions. Games have traditionally followed this path
over time.

Crysis will be released in 32 and 64bit versions
as well as some other upcoming releases.
this is why i'll be installing the 64bit edition.
