I do not see 64 bits as something important.

I think 64 bit is very important.
Do we have to have 64 bit now? no, things are going just fine for home use and
in commercial networking, but there will be benefits.
Do you believe we have benefited from going from 16 bit to 32 bit?
When 1000's of technicians in many fields focus on 64 bit, I believe good things
will happen. The speedup will probably be similiar to an average upgrade for
chess programs. Many benchtests on internet now.
This 64 bit will be my next upgrade for my dual processor gamer.

The major differentiator between 32-bit and 64-bit Windows is in memory support.
Currently, 32-bit Windows is capable of supporting up to 4 GB of system memory,
with up to 2 GB of dedicated memory per process. Windows XP 64-Bit Edition will
currently support up to 16 GB of RAM, with the potential to support up to 16
terabytes of virtual memory as hardware capabilities and memory sizes grow.

Customers will find some feature differences, but overall, 64-bit Windows
includes a majority of the features that are included in 32-bit Windows.


large memory support and increased floating point speeds. Windows XP 64-Bit
Edition allows these large data sets to be loaded into memory for rapid access
by the processor. Since data in memory is accessed about 10,000 times faster
than it is on a disk drive, analysis can be performed quickly. However, 32-bit
processes cannot load 64-bit dynamic-link libraries (DLLs), and 64-bit processes
cannot load 32-bit DLLs.

While 64-bit hardware will be compatible with many 32-bit applications, 32-bit
applications will perform better on 32-bit hardware. WOW64 is intended to run
32-bit personal productivity applications, enabling new levels of creativity and
collaboration.


Q.  Will my applications be faster on Windows XP 64-Bit Edition?

A.  Applications that require large-memory addressability (beyond the 4 GB
memory limitation of 32-bit architectures) should benefit immediately from
performance increases on Windows XP 64-Bit Edition. Over time, more and more
ISVs are expected to migrate their applications to take full advantage of the
scalability and memory capacity provided by Itanium-based workstations running
Windows XP 64-Bit Edition. Most 32-bit applications should continue to perform
best on 32-bit versions of the Windows operating system. To learn whether
specific applications will be migrated to 64-bit versions for Windows XP 64-Bit
Edition please contact your ISV.
