I'd vote to just do ~4.8ghz or so. The relatively big increase in power usage(and temps, voltage, etc.) vs. relatively small increase in performance make me come to this conclusion.

Short answer, yes. But don't you just start at a low-ish voltage and work your way up until you find something stable? Over-estimating seems to take longer, since you could be 0.01V over what's 24 hours stable.. and there's (possibly) another day of testing
If your CPU is only stable up to say 1.48V, at any given clockspeed(hypothetically let's say, over 1.48V at 4.8 is a no-no), then 1.5V at 5ghz would be unstable. Perhaps you could still get stable with 5ghz at 1.48V, but it wouldn't necessarily have to.
