i386, i486, i568 and i686 are all 32-bit systems. x86_64 refers to
any 64-bit thing running on an Intel 64-bit processor (Xeon, Centrino
Duo-core, etc. or any that supports the E64T extensions) or AMD 64-bit
processors (Athlon X2, Opteron, etc.). Note also that the 64-bit
machines above will happily run the 32-bit operating system as well.
The reverse is NOT true...the 32-bit machines can NOT run the 64-bit
operating system.
If you want maximum compatibility, run the 32-bit stuff regardless of
which processor you have. There are still gaps in some third party
software support of 64-bit (e.g. there's no 64-bit Flash player). You
really only see a big performance improvement using 64-bit stuff when
the task is compute-bound.
