Ok well I was "thinking" about getting vista when the SP2 comes out... But I know there is X64 ultimate version an a x86 version? Whats this x86 version? I have a x2 3800+ which supports X64 OS... Thanks for the help!
 
Thank you, Also how do u find out what version of Xp you have? My uncle installed my XP on my computer. It is Xp Pro SP2... Is there a place I can look or anything?

Also, if i have x32 XP, can I upgrade to x64 and still have all drivers/programs/games be in working order?

Just right click on "My Computer" and select properties and it should say there.

And it's iffy right now about about 32bit programs running perfectly on a 64bit OS.
 
All it said when i reclicked on my computer, is
System: Microsoft Windows XP Professional Version 2002 Service pack 2

Computer: Specs of computer.
 
Unless you have a program that is specifically designed for 64bit I would stay away from 64 bit windows. The driver support is not as good as it is for 32bit windows and also program support and performance is not as good as well.

The main disadvantage of 64-bit architectures is that relative to 32-bit architectures the same data occupies slightly more space in memory (due to swollen pointers and possibly other types and alignment padding). This increases the memory requirements of a given process and can have implications for efficient processor cache utilization. Maintaining a partial 32-bit model is one way to handle this and is in general reasonably effective. In fact, the highly performance-oriented z/OS operating system takes this approach currently, requiring program code to reside in any number of 32-bit address spaces while data objects can (optionally) reside in 64-bit regions..

Currently, most commercial software is built as 32-bit code, not 64-bit code, so it can't take advantage of the larger 64-bit address space or wider 64-bit registers and data paths on 64-bit processors, or, on x86 processors, the additional registers in 64-bit mode. However, users of free or open source operating systems have been able to use exclusive 64-bit computing environments for years. Not all such applications require a large address space or manipulate 64-bit data items, so they wouldn't benefit from the larger address space or wider registers and data paths; the main benefit to 64-bit versions of applications that wouldn't benefit from them would be that x86 versions would be able to use more registers.
