Today, 64 vs 32 bits in one of the few really frustrating remaining
problems with Linux.
If you have 64 bit linux, a lot of 32 bit apps won't run... if not
all... and vice versa.
The only OS that handles that well is Solaris. It installs with 64 AND
32 bit libraries regardless of which mode you run it in (you can decide
at boot time)... and your applications can be written for 64 or 32 bit
mode, they will run. You can run a very old Netscape navigator in 32 bit
mode on a fancy AMD64 Solaris machine and it will run just fine...
provided your Netscape was compiled for x86 (not SPARC).
With Linux, unless you really NEED 64 bit addressing (for example
because you are manipulating huge data structures, or files, or because
you are driving simultaneously 4 graphics cards with each over a 1GB of
video RAM) then you should avoid 32 bit mode. In many cases, it will
slow down your system. In most cases you will have application
compatibility issues unless you know the apps you will be using are
available in 64 bit mode.
My suggestion, (re)install in 32 bit mode. (Unless, as I say above, you
really need the addressing capabilities of a 64 bit OS).
