With US $566.75 price tag
the recent leak pre-order of the Zotac GTX 680 in Europe, a US based e-tailer has also jumped the gun and listed Asus' GTX 680 for US $566.75.
Although, we don't get any new information from these two leaks, other than the Asus' GTX680-2GD5 part number, it gives a general idea regarding the launch price of the GTX 680. Early listings are, of course, usually way too high, but now the US $549 launch price looks a far more real.
As always, the launch price isn't carved in stone and it is something that Nvidia can easily change but don't get your hopes up as we don't expect a miracle.
