Only testing will reveal the true situation.
Only other point I'd mention is that on a 3.4 Prescott, even with dividers, you are still going to be limited: look at how much trouble Intel are having just getting the 3.6GHz model out the door; it's already months late, and even that's probably on a newer stepping. Hence I think if he's looking to get much beyond it's default speed, he's gonna need very good cooling - which is expensive.
