Do you think Windows has too many versions? Well, aside from the four boxed you see, you now have two more choices for each. Do you go 32-bit or 64-bit?

Computers are rapidly moving to 64-bit processors. The main advantage is they allow you to install more memory. A 32-bit system is limited to 3.5gb of memory. 64-bit versions of Windows 7 allow you to install up to 128gb. More RAM means better multi-tasking and makes certain programs faster.

While most programs are still 32-bit, there is no reason not to go 64. The cost is the same. Programs that are specifically coded for 64-bit also run a little faster (about 10%) compared to their 32-bit counterparts.

If you have a processor made after 2006, chances are it is 64-bit. This includes all Intel Core 2 and AMD Athlon64 processors and later. You can tell what CPU you have by looking in the BIOS or right clicking on "My Computer" and selecting "properties".
