Chuck, I don't know much about it except what I can find from MS. (see
below) I'm not sure I can find drivers for all my old hardware nor could
I run old apps, access old data. And it looks like an upgrade to PS CS2
would be necessary. MS also says that unless your file size exceeds 2gb
maybe 32bits are enough. Running XP HomeEd I'm looking at the 3gb RAM
limit so if going Pro why not 64bitPro? Big $$$ to do all this though.
Anyone been there, done that?

> *Important considerations*
> Because Microsoft Windows XP Professional x64 Edition is relatively
> new and is based on fundamentally different technology architecture
> than the 32-bit version of Windows XP, you should consider several
> factors before adopting Windows XP Professional x64 Edition:
>
> •
>
> *Devices: *Windows XP Professional x64 Edition requires 64-bit device
> drivers. This means that the manufacturers of the printers, keyboards,
> and devices you regularly plug into your PC must have device drivers
> that work with Windows XP Professional x64 Edition. Please check with
> your device manufacturer to verify the availability of 64-bit device
> drivers.

> *Software: *New applications—like the ones coming out for digital
> content, engineering, and gaming communities—are often built to run on
> 64-bit systems. You may already have 32-bit software that can run on
> Windows XP Professional x64 Edition. Widely used programs, such as
> Microsoft Office 2003 and Adobe Photoshop CS2, run on Windows XP
> Professional x64 Edition. However, there are some known
> incompatibilities with 32-bit software. For example, because Windows
> XP Professional x64 Edition does not support 16-bit software, older
> programs may not run on it. In addition, software that includes
> kernel-mode drivers—such as antivirus packages and back-up
> applications—must be 64-bit native to run on Windows XP Professional
> x64 Edition. It's a good idea to check with the company that makes
> your software to find out if it runs on Windows XP Professional x64
> Edition.

> *Migration: *Whether you are moving to Windows XP Professional x64
> Edition from a 32-bit operating system or simply experimenting with a
> trial version, it's important to note that migration requires you to
> “wipe and reload” your operating system. In other words, when you
> install Windows XP Professional x64 Edition, it will overwrite the
> preexisting operating system. You can save your files and settings and
> take advantage of the Windows Migration Wizard, and then reinstall
> your applications and devices once you are working with Windows XP
> Professional x64 Edition.
