Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

So if he will be doing such activities, there is likely a good reason to use 64 bit software.
As I said in that other thread, the real performance difference may be an effect of gcc default behavior, rather than an true difference between 32 bit and 64 bit modes in the architecture. But that distinction doesn't matter to an ordinary user. If you can't or don't recompile the software to make best use of SSE in 32 bit mode, then you only get those benefits in 64 bit software. For compatibility and/or other reasons, precompiled 32 bit won't make best use of SSE.
I use 64 bit Mepis distribution myself. I've read about hassles such as pinniped mentioned (post #5 of this thread) but I've never encountered any myself. I open pdf files when needed and never thought to even check what software is running to do that and whether it is 32 bit or 64 bit. It just works. Similarly Flash seems to just work. I don't use Skype.

But we don't seem to have any good guidelines for where 64-bit is appropriate.
D'oh - what I meant was I use only 64-bit O/Ss when I have 64-bit capable hardware. For me that is sufficient (and appropriate)
I accept this doesn't offer any assistance to anyone about what might work and what might not.
Just check the settings first whether its 32 bit or 64 bit
U can get a idea of it
by looking into /proc/meminfo
if its 64 bit then go in for fedora that is compatible with 64 bit.
else just go in for 32 bit os
A "Core Duo" is 32-bit. A "Core 2 Duo" is 64-bit. If you have 64-bit hardware, you should run 64-bit software. The only issue, except with proprietary software, is Java applets in your browser, and there are ways to handle that.
(1) Is your processor 64-bit capable (meaning that it can run 32-bit or 64-bit OSs)?
(2) Assuming your processor is 64-bit capable, do you want to use a 64-bit OS?
To find out the answer to question (1), I would recommend looking in your friend's computer's manual. It might say there. Alternatively, if you know or can figure out the exact model of the processor, then a search on Google or Newegg.com might turn up the answer. If your processor is not 64-bit capable, you must use the 32-bit version. If it is 64-bit capable, you can use either the 32-bit or 64-bit version.
If your processor is 64-bit capable, you have to answer question (2). As I understand it, there are both benefits and drawbacks to choosing the 64-bit version. The main advantage is potentially getting better performance. The main disadvantage, on the other hand, is that there could be software that does not run properly on 64-bit OSs.
It is your call, but if you friend just does normal web browsing and office stuff, I would go with the 32-bit version.
I will suggest you go for the x64 version. Like someone wrote if your system is not 64-bit the DVD won't boot! BUT if you decide to install the x32 version is fine just remember if later on there is a new release and try to upgrade it make sure you use the x32 version as well.
I had installed Suse 10.3 x32 on a Intel core2 duo and I upgraded to SuSE 11.0 x64 version which works fine until I tried loading KD4 I got an error message.
hope this helps!
