Well, it will be a little faster. (Whether it is a wise upgrade, depends
on how much you are paying for the processor. You can also get a cheap
motherboard, and a more modern processor, and reuse your old video card
and memory. But what you propose is certainly a lot less work.)

The returned list for A7N8X Deluxe is here:

Athlon XP 2500+(333 MHZ FSB)(Model 10)(Barton) 1.04 1002
Check PCB and BIOS versions before flashing BIOS!
The A7N8X Deluxe come in several revisions. The "1.04" number is the
minimum motherboard revision. If you look at the motherboard
surface, in white letters it should say "A7N8X Deluxe" and nearby
it would say "Rev. 1.04".
The minimum BIOS revision listed is 1002 or later. There may be
a sticker on the motherboard BIOS flash chip (the chip in s square
socket), and the release number of the BIOS could be printed on
the label. If you have already flashed the BIOS, you may have to
check the BIOS screen(s), to figure out what you flashed it with.
If the BIOS revision is too old, it may need to be upgraded _before_
you install a new processor. But rather than complicate matters,
you can check the particulars of your motherboard and report
back here if you need further help. Asus sticks BIOS updates for
several revisions of motherboard, on the same web page, and the
owners of those motherboards must use caution in selecting the
correct file download for the job.
A "retail" version of chip, may come with a heatsink/fan designed
for the processor. Chips of the "OEM" variety, do not ship with
a heatsink/fan. While your Duron has a cooler on it already, it
is hard to say whether that is the best cooler for the job. (I
use an aftermarket Zalman 7000AlCu cooler on my AthlonXP mobile,
and it stays quite cool.)
It should be a simple matter of installing the new processor, putting
some thermal paste on the silicon die of the processor (being careful
not to smear it on the bridges on the top of the chip). Only a thin
film of thermal paste is required. The purpose of the thermal paste,
is to displace any air gaps between the cooler and the processor.
Be careful when installing the heatsink on the top of any processor
with a bare silicon die. If the heatsink is tilted on an angle, and
is not perfectly flat, you can chip the edges of the silicon die when
installing it. In my case, one of the benefits of the Zalman 7000
series cooler, is it fastens in place with screws, and it less dangerous
to install than a cooler with clips. Some people have used small rubber
disks with adhesive on them, and four disks are placed, one in each
corner of the top of the CPU package. The rubber bumpers help
prevent the cooler from being mounted on an angle. The rubber material
must be carefully selected, to be the same height as the silicon die.
If the disks were significantly taller than the silicon die, a lot
of the compressive force applied by the heatsink clip, goes into compressing
the rubber bumpers. Leaving less force to keep the heatsink in contact
with the silicon die. Fortunately, thermal paste does not require a lot
of retention force, to work well, so this is not a big issue.
What to use for a thermal paste ? You may be able to pick up some
thermal paste, from the same source as your new processor. Every
person has their own views on which brands are best, and the only
product I don't really like, is some of the cheap zinc pastes that
have a liquid consistency. The problem with those products, is the
carrier tends to leave the area between CPU and heatsink, and no
matter what product you select, you do want it to stay between the
heatsink and CPU. I currently have a tube of AS3, that has lasted
me forever. It seems to work well enough.
I find the safest way to install a heatsink/fan, is to remove
the motherboard from the computer case. That allows me to visually
examine the fit of the assembly on all four sides, before installing
clips or tightening screws. For this method to work, the combined
dimensions of motherboard plus cooler, must fit into the opening
of your computer case. I have one computer case, where a crossbar
prevents installing a motherboard with the cooler already in place.
I find there is a small bit more risk, if I have to install a
heatsink while the motherboard is still inside the computer case.
Some people have damaged their motherboard, due to the technique
they use to push down on the heatsink clip. Some clips have a
raised bit of metal on the top of the clip, and it is tempting
to use a slot head scredriver, to push on the clip. That can slide
off, and hit the motherboard. Sometimes the impact will cut a copper
track or break off a resistor on the motherboard. A recommended tool
for the job, is a "hex driver". The six sided opening of a small
hex driver is placed over the raised bit of metal, and that helps to
hold the hex driver in place. It cannot slide off as easily, so the
risk of damage is reduced.
You might be able to find installation guides, for putting on the
heatsink. I found one here, but the pictures are pretty poor in
this one.
