32 bit vs. 64 bit

[andygoaly]

I am building a new system and was browsing operating systems when I found out that there were 2 versions. 32 and 64 bit. How do I find out which one is compatable with my system. Any answers are appreciated!!

If you are building a new system, either should work fine, unless you are using a VERY old processor.

In general though, you should go with a 64-bit system, as you will be unable to use more than about 3-3.5 GB of RAM with a 32-bit OS. Most modern builds go with 4-6 GB of RAM.
