Answer 2

There are a few differences between the two types. x64 can run twice as many colours than x32, giving a much better looking image than you would be used to. Also, performance-wise, x64 is much faster than x32, and the difference is immediately noticeable. Besides that, on an x32 system, the max amount of RAM that can be installed is 4GB, whereas on Vista Ultimate x64, you can have 128GB.

The main disadvantage of x64 (on XP mainly though) was that alot of programs still aren't compatible, deciding to stay with x32 for a little while longer. But seeing as Vista is primarily an x64 system, that problem won't be around much longer.

Hope that helps=]

Answer 3

I don't know but I heard that 32 bit was a-lot better because it is more compatible with programs!

Answer 4

like the previous answer, 32 bit XP supports a lot of programs.

However, the difference between 32 bit and 64 bit is when reading RAM.  For instance, if you insert total of 4 GB ram into your computer, 32 bit OS will detect only 3.2 GB, while 64 bit will detect total of 4 GB. So it really depends on whether you are having 4GB RAM or plan to upgrade or not.  If not, then 32 bit will do
