Those are some very nice components. Really good ram, and a nice PSU. Most people dont realize the importance of a good PSU, but you do. good work. The MoBo is great, I have heard nothing but good things aboput DFI when it comes to Ocing. I dont think I have ever heard anything bad about DFI, pertaining to overclocking or otherwise. Apaprently their voltage regulators are very good too, as they automatically bump themselves up when they realize there is not enough power supplied to the board. Quite smart, if you ask me.
Bump up a little and get the AMD 3200+ Venice. It is not much, but they OC better than any other processor, including the 3500+ Venice and the 3000+ Venice. I cant give you a guesstimate on your speeds, but it seems senseless is not quite so senseless when it comes to this topic.
Have tons of fun, and make sure to post your results! Also, are you ever going to go with a supercooled solution? Phase change or the like? You totally should, then you can get some seriously crazy speeds out of that!
