you will not notice that 64bit looks any different. but no, not all your software will work. some work in both versions and some are 32 or 64 specific. you will have to check software sites to see if they have a compatible version or not.

i second that

90% of software will work as normal. 8% of software may require you download the 64-bit version, but otherwise will function the same. 2% of software won't work and won't have a 64-bit version.

I sincerely doubt you have or will ever have any software that won't work though, and drivers are no problem these days.

Most software will work normally, but not all.

The differences:

XP 32-bit scores higher in everything non-64-bit than XP x64. But XP x64 is much more stable and much cleaner. I've used XP x64 for an extensive period of time before going back to 32-bit. It's not that XP x64 was terrible; I just needed all the FPS I could get with my aging hardware

Not true, I got considerbly higher FPS in xp64 with my old rig (my current rig can't run on xp 32 lol).

Any program should run fine unless it's 16-bit.

Hmm... My tests showed me the following results:

Doom 3: XP x64 got 10 FPS lower than XP x86
Super Pi: XP x64 got 2s slower than XP x86
3D Mark 03: XP x64 got ~700 points lower than XP x86

My only guess is the WoW64 emulator thing... But anyway, that's what my results were. Also, you know that 64-bit OSs provide no performance gain for 32-bit programs, right?

Not quite correct. The 64-bit architecture doesn't provide any performance gains, but XP x64 is based off a different and newer kernal then xp32 (which is why it's more stable).

If you're getting lower scores, I would say somethings wrong in the driver department. Most of my XP x64 use has been with ATi cards, the nvidia machine I have runs server2003. Perhaps Nvidia didn't have the best drivers when you did the tests, or doesn't have the best ATM.

Yeah, I got the feeling XP x64 was more stable and clean than x86 (the former is based off of server 2003, I believe.)

What would my Super Pi (CPU) benchmark have to do with nVidia drivers, though...

This performance drag was like that of XP--vista. My XP x64 was fast for desktop work and stuff, but when it came to raw performance, XP x86 beat it in every aspect.
