PAX East 2011, which kicks off tomorrow, is widely expected to finally deliver a dual-GPU solution from NVIDIA's Fermi family of graphics chips, a PCI Express-saturating single-card workhorse to be known as the GTX 590. While we wait for its arrival, however, here's a sentimental look back upon 2010 and another little prototype that NVIDIA had kicking around its labs back then. Emerging over in a Chinese forum, this dual-GPU board features two GF104 chips (the same that made the GTX 460 such a winner) and a snow white PCB paintjob that makes it look utterly irresistible. We're loving the four DVI outputs and, just like you, have no idea why this card never came out, but that shouldn't obstruct the enjoyment of looking at the darn thing. More pics after the break.
