If your SB 2700K OC'd pulls 219W at load and IB looks to be around 20% more efficient, we can expect it to pull around 180W from the wall with a similar overclock. Maybe even less as I've seen some stupidly low V-Core numbers for 4.5+ GHz performance.
This would mean that 2.33 OC'd Ivy Bridge 3770K boxes will pull the same wattage as a 2P, Xeon E5 2687W. If we figure an OC'd Ivy will be scoring ~11 CineBench points, then watt for watt, it delivers 25.63 CineBench points compared to 25.5 for the Xeons.
So while I did not provide facts to back up my hunch, my hunch was well founded based on the numbers I've generated from my own OC'd 2600Ks, 3930Ks and from reading several of the Xeon reviews. It's not quite the efficiency increase I first had in mind, but after I posted I realized that I wasn't fully taking into account the power required by all the auxiliary bits of 3 systems compared to 1 (1 HDD to spin, less RAM and chipsets to power, etc).
