Just a little thought. If he is not overclocking, there is no real need to pay the extra bucks to get Pro2, where the main features are the multiplier and FSB settings. Sure the Pro2 is even more stable, but to me (not a perfection), Pro1 is good enough. Remember it powers 4 of our AnandTech Servers 🙂
But I do agree Pro2 is an awesome board. Just my 2 cents.
