"It would take massive overclocking of about 6GHz to be on the same level as the Haswell i3. Maybe you have a few tanks of liquid nitrogen..."
Well, Overclocking the FX by a few 100Mhz is a bit too mainstream, so extreme Overclockers OC it by a couple GHz, and since our conventional EVO 212 can't keep such a setup cool, a few tanks (not many, just a few) of Liquid nitrogen along with an OC bench help those overlcockers with keeping that setup nice and cool.
His point was, you'd need to seriously OC the FX to put it on par with i3.
