64-bit - Not recommended for daily desktop usage

[Kent Borg]

The benefit of 64-bit is that you can address more RAM.

32-bits can only address 4GB of RAM.  If you have less than 4GB then
there is no benefit, in fact I think executables are ~slightly~ larger
in 64-bit, so you lose some capacity.  If you have more than 4GB then
you need the 64-bit version to get to all your memory.  If you have
exactly 4GB then I think 32-bit Linux keeps you from using some of your
RAM, but I don't know what the loss is these days on an x86 machine.
