Hi was curious about something for those that know about Windows XP 64 Bit And Windows XP 32 Bit that a computer can use any of theses 2.
Which one is better 64 bit or 32 bit Post your Comments please and vote in poll.

It's not a case of which is better.
If you have a 64-bit CPU and are able to find hardware drivers for all your devices, then go 64-bit.
But still, some hardware doesn't have 64-bit drivers and so your stuck with X86 (32-bit).
It's only really beneficial if you have 4GB or more of RAM.

As for Vista, If you have a modern computer and it has 4GB or more of RAM, then it's likely all drivers will have 64-bit versions available, in this case, go 64-bit.

There aren't huge performance differences and 64-bit hardware still runs 32-bit software, so it's not really a matter of opinion, more what's possible from your hardware.

XP-64 never really taken off, because at the time, there weren't much driver support and Vista was on it's way.
With Vista, If drivers allow, I'd always use 64-Bit. The support for 64-bit vista is much greater.

I use Windows 7 Beta x64 and it's quite nice.  

But as for "which is better", there's more involved than just software.  

I would have to suggest Windows XP 32bit over x64 because it's more supported as far as drivers and software is concerned. I use Windows  Vista Home Premium x64 no problem. All of my hardware is supported because the drivers came bundled with  my HP laptop. In the next 5-10 years I would suspect that 64bit software will become the new platform, gradually phasing out 32bit and 128bit processors will be in development. I tried Windows XP x64 when it was in beta and I was not happy with it at all. It was very buggy, but I haven't tried it since to compare.

The question is ,"Who would benefit for buying a 64-bit system?" The answer: mostly businesses, universities, scientific groups, and government. If you produce videos, computer art, or develop programs, 64-bit systems will be helpful. But for the home user, 64-bit is currently a bit overkill. You won't see faster activities like writing, spreadsheet processing, or web browsing so (in my opinion), save your cash for something else (like a bigger hard drive or more RAM).

You will also need a 64 bit system and drivers that support 64 bit and these are still not 100% available.

I would wait.

While what others have said is perfectly correct, it's quite difficult to actually buy a 32-bit CPU now... All/most on the shelves are 64-bit... They'll of course do 32-bit too.

Thanks wasnt going to buy it lol my computer is running 64 bit ultimate vista and i have notice 64 bit ultimate vista is faster then 32 bit ultimate vista which i had the 32 bit vista and changed it to 64 bit vista since it seems much faster to me not sure if you will agree on that.

I run 64 bit ultimate vista. It runs nicely. Given that all my hardware has capable X64 drivers, I wouldn't run anything less than X64. It really depends on your hardware.  

Another advantage that 64bit operating systems allow is higher memory addressing. That means you can go above the 2GB RAM limit assigned to 32bit operating systems. Windows Vista Ultimate x64 boasts that it can support up to 16GB of RAM, not that a home owner would need that much RAM with today's software. I have 4GB of RAM on my laptop and it runs Vista Home Premium x64 quite well. Most processors sold with new computers are dual core too. 64bit operating systems also allow for better optimization of dual core processors. This grants processes to be split up between the two cores, allowing true multi-tasking.

As said already if your computer supports it and you don't have trouble finding 64bit drivers, go with 64 bit.  There will be at least a minor performance gain.

I wish M$ would've held off on Vista for a while and actually put some time and effort into XP64 and into getting vendors on board, getting drivers written for it.

I never did switch to XP64 or Vista because I had some very specific external hardware that had neither Vista nor XP64 drivers and systems I've used with Vista are a pain.

The 32bit ram limit is an oddly around approximately 2700 megs.  2783 maybe.  It's odd that that's the ceiling.  It's like someone else at M$ re-iterated Bill Gates famous mistake of "who would ever need more than 640k of main memory?"...... Thanks Bill.  Anyone else remember those issues from back in dos?

I'll hold out for Windows 7.  I've heard very few bad things about it.

There should always be a performance boost when switching from a 32bit version of one OS to a 64bit version of the same OS.  On the other hand, I did a recent reinstall of Windows XP SP3 and thought that took long.... on a slower older computer.  That was until I was on a newer computer with vista "preinstalled" and it took longer for Vista to "configure" itself and install all the drivers automatically then it took me to install XP on an older machine and install all the drivers by hand one at a time since I didn't have the mobo cd.  Hmmm...

I have got a 64 bit dual core laptop but I am not wanting to change to 64 because I am happy with 32
