It appears that Asus is also building a GTX 660 Dragon Edition card.
Asus is releasing a new graphics card: the GTX 660 Dragon Edition. The card's model number GTX660Ti-DP-2GD5 somehow has the "Ti" phrasing in it.
The card's cooler is almost identical to the standard DirectCU II TOP cooler, with the exceptions of the blue stripes (instead of red) and a backplate to cool the memory chips on the rear of the card.
Concerning specifications, the card features a GPU Boost speed of 1,150 MHz and 2 GB of GDDR5 memory running at 6 GHz over a 192-bit interface. The card will also feature Asus' Direct Power vGPU passive signal-noise dampener.
So far, there has been no word on pricing nor availability.
