The EVGA card is a "superclocked" edition with a 1085MHz base clock—same as the stock boost clock—and a boost clock of 1137MHz. The combination of the aluminum-and-magnesium cooler and the tweaked clocks will set you back $459.99, which is $50 more than the price of EVGA's standard GTX 770 with a plastic-shrouded cooler.
Worth it? I dunno. Multiple brands offer GTX 770 cards with dual- and triple-fan coolers that are likely to be plenty effective for 400 bucks. None of them look like an iPad got wrapped around a Kepler GPU, though. They're also not designed to exhaust warm air out of the case as effectively as the Titan-style cooler.
Hat tip to TR reader John L. for the heads up, by the way.
