It looks like we're not quite done with news about the Nvidia GeForce GTX 680. As our review showed, the card is pretty amazing and is still efficient while being amazing. Pictures have surfaced of a Galaxy-brand GTX 680 which is cooled by a single-slot cooler. This is made possible by the amazing efficiency of the new Kepler architecture.
195w TDP is pretty high to be handled by a single-slot cooler, so frequencies should be expected to be reference or below. This device certainly will be nice for smaller, mid-tower PCs or for a cramped PC in which you want to run SLI. No release date or specifications have been released. For all we know, this could be a prototype that never sees the market.
