Check the website, I'd be concerned the power management of the older board will hinder overclocking. Those 8500's are plenty fast and have a nice high multi so squeezing that last bit to get you to 4 isn't too terribly taxing when you consider that lots of mobos break the 500 fsb barrier now adays. i'd consider shopping for a decent p45 or even keeping your eyes peeled for deals on x48 boards. cheers!
