Most of us aren't psychic here, so you may want to post what the "old
Motherboard" model is.
There are a lot of "old motherboards" around here that I have
done upgrades like with, including very common models like the
ECS K7S5A, and the Asus A7N, A7V, and A8N lines. So long as your
motherboard has an nForce, nForce2, KT266A, or KT400 chipset I
think the odds are in your favour. Other chipsets may work just
as well - I just can't recall having done that kind of cpu
upgrade with them.
The most recent similar upgrade I did was going from a Duron 1300
to an Athlon 2400 on an Asus A7N266-VM.
