Yeah, but the person who decided to call the 64bit ISO -amd64 is
equally wrong.  If this was still back when you needed separate builds
for AMD64 and EM64T that would be one thing, but since that's not
really required anymore, a more generic term would be far more
appropriate and less confusing...  x86_64 would be nice... x64 would
be too, though someone may confuse that with IA64 for some reason, but
not that many people know what an Itanium is anyway.. and the ones
that do would be smart enough to know the difference between them...

For the OP:

Steve and Amedee gave you the answer :-)  the reason you'd want that
is 32bit won't make as efficient use of your 6GB of memory.  If you
had 3GB or less, 32bit would be fine.  at 4GB, 32bit still
realistically only gives you 3.5GB.  64bit should give you full use of
your 6GB for the most part.

A note of warning though...  64bit will run both 64bit and 32bit apps.
 When you install software, you'll want to get the 64bit programs when
possible.  You'll find that in many cases, a given program will be
available in both 64bit and 32bit versions.  For cases where there are
only 32bit versions, those should work fine on a 64bit system.

And because I throw the term 64bit around loosely... in this case,
64bit = amd64 or x86_64 or x64 (all one in the same now) and does not
mean IA64 (completely different processor architecture).
