Well the amount of voltage drop depends on how the 'droop mode' of the regulator is configured. Mine used to drop from 1.76 to 1.68V under load but now with adjusted Droop it stays at 1.76-1.74V all the time.
And as far as ASUS powersupply goes it seems to be one of the best if not the best out there. Atleast this mobo gives the highest CPU OC :) And seems to handle 5GHz too :D
Droops mod discussed at http://metku.net/index.html?sect=view&n=0&path=reviews/asus_p4p800/index_eng
Last mod was vcore mod. 1.95V is maximum Vcore, but idle and load voltage difference is quite big. This is normal and follows Intel specs but overclocking is much easier with stable Vcore. Solution is to add ~250Kohm variable resistor between CSCOMP and CSSUM pins. (Datasheet of ADP3180 can be found here) This adjust droop voltage. I didn't solder mod straigh to the legs but to easier locations.
