We'll be honest with you, we thought the GTX 480 was finally a graphics core too damn large and power-hungry to get the dual-GPU treatment. ASUS, however, is making us think again. Imagery has emerged of a Mars 2 (or II, if you're into outdated numbering schemes) reference board that fits two 480s on its densely populated surface, and is fed by not one, not two, but three 8-pin auxiliary power connectors. Back when Galaxy showed off a dual-GTX 470 prototype at Computex a month ago, we deemed it an unreasonable proposition -- in terms of power draw, heat dissipation, and cost -- but apparently those Taiwanese focus groups are really into their extravagantly overpowered video cards. We suspect if and when this Mars 2 hits retail it'll do so in a highly exclusive fashion, like its predecessor, and anticipate the unveiling of its cooler -- which is likely to be either the biggest or best engineered one we've seen yet.
