Hello,
Does CentOS 5 use a better approach to 64-bits and 32-bits packages existing on the same machine?
How is Upstream package selection comparing 32-bits and 64-bits editions?
Should we expect third-party repositories (mainly rpmforge) to better support 64-bits packages?
I want to figure out if I should use CentOS/RHEL 5 x86_64 in desktop environment.

Better than what?

Not quite sure what you mean here.

rpmforge has always had good 64bit support.

You'll probably run into the same issues as centos4 for desktop use. Still no 64bit flash, not too many browser goodies, etc. The basic stuff works fine, it's the 'free proprietary' software where the issue is mostly.

Than CentOS 4 and its package management concerning 32-bits and 64-bits packages in the same machine.

The package selection for 32-bits and 64-bits are quite the same or there are important differences? Example: no Acroread (-plugin), no Flash plugin for Firefox, etc. Well, that is an important difference for some users (maybe most). Ok, now I see you've answered this below.
SLED deals pretty well with this - like firefox 32-bits and flash/acroread out of the box. I like the way it deals with 32 bits and 64 bits coexisting in the same machine.

A better approach as compared to what? CentOS uses */lib64 and */lib as opposed to Debian based distributions that use a chroot for 32 bit applications.

From what I can see on the beta, everything available for 32 is
available for 64 bit. I run a fully 64 bit machine for a while (before I had to send my machine back for fixing) and it seemd to work just fine.
You will have some problems with closed source software such as flash, as they're compiled for 32bit. I know there are ways to get around it (running a 32bit version of the browser or running a "proxy" app that allows you to use 32bit plugins) but I haven't used any of them as I was trying to run a "pure 64bit" machine.
I want to figure out if I should use CentOS/RHEL 5 x86_64 in desktop environment.
I used it and was quite happy with it. In my system (AMD X2) it seemed more responsive than my previous machine (Core Duo) but I do think that much of that difference is due to hd speeds.

What benefits do you see to a 64 OS on the desktop?

You probably won't keep bumping into things that still accidentally have a 2 gig file size limit like you do with 32 bit linux (even though it hasn't been necessary for years). And your clock will keep working past 2038.

I'm really hoping that they fix that before 2038! Besides, I'm hoping I am retired by then. ;-D

Please, let Leonardo say what _he_ thinks important. It's his computer.
As for the 2 Gbyte filesize, I know just one program with the problem.

I agree with you John. Nowadays I think 32bits systems are better for a desktop-boxes. ¿Reasons? Well, the main reason is there are a lot of applications that hasn't been ported to 64bits.

Better performance.
And I want to run other systems inside VMware - including 64-bits guests.
So x86_64 might bring some benefits - or some more headache.

I think the ability to run 64-bit VMware guests depends on the CPU capabilities, not the host OS - and not all 64bit CPUs will support it. Unless things have changed recently, you actually need some 32 bit libraries to run VMware.

How about just plain faster performance when you have a 64-bit CPU?
