The overall answer

32-bit Operating Systems are the most common platform, and most software is written for 32-bit platforms. The Newer 64-bit Operating Systems can take advantage of newer hardware and software technologies but as of this entry, the majority of the software out there is written and only uses 32-bit technology.

Why would you use a 64-bit OS then?

The reasons are this: If your computer has more than two processors (CPU’s) or you want to take advantage of more than 3 Gigabytes worth of Memory (RAM) then you may want to use the 64-bit version of the OS you use. If you don’t use a lot of applications that are built for 64-bit platforms then you really won’t notice much of a difference.

Why wouldn’t I want to go 64-bit?

There are a lot of programs written for 32-bit platforms that have problems running on 64-bit Operating Systems, and the selection of 64-bit software out there isn’t anywhere near the amount of titles that are written for 32-bit computing. This is slowly changing but if you have a program you HAVE to use and it doesn’t work on 64-bit platforms then stick with the 32-bit platform. Another factor to take into consideration is the hardware your computer possesses. There are quite a number of dual-core computers out there that they paste 64 after the name even though they are really two 32-bit processors, thus making the 64-bit claim. Some of them can run the x64 platform but whether they should or not is arguable.
