How does this affect thuban vs. deneb. I've seen where oc'ing cpu-nb greatly increases performance, but have personally had trouble getting it past 2700 or so. I've been following "Dolk's Guide" and the chart as to what voltage to use for cpu-nb at what frequency. How does mb-nb voltage play into to this? I'm being cautious about what i'm doing and gathering as much info from as many sources as i can.

How far you can push is going to change from chip to chip, and set up to set-up. Even though the Thuban has a better IMC than the Denab chips its still great to overclock them, you still get performance boost. Your chip just might not like going past 2600, you might need more voltage, or better cooling, who know's.
