Too much logic in here, time for some irrationality!
If I had a 3930k, you can bet I'd be making that chip beg for mercy. They overclock quite well, and as you can see from my sig, I like to push my hardware to (and past) its limit.
I find the process of tweaking the hardware to get more performance to be a lot of fun, and who knows, maybe you will too. You certainly won't get any additional gaming performance out of overclocking it, but with a decent cooler you should be able to hit 4.5 GHz without too much trouble.
