The board will only be 22.5cm long, much shorter than the original 33.5cm cards that are shipped to OEMs only.
The core is clocked at 500MHz while the GDDR 3 memory runs at 1200MHz. Each chip addresses 512MB of memory, meaning that each card has 1024MB memory or that Quad SLI totally features 2GB of graphic memory.The price for a single card will be about $750, so to use Quad SLI you'll need to spend about $1,500 for your graphics cards alone!
Each card comes equipped with two Dual link DVI-I connectors and seven-pin HDTV out. The card supports HDCP and we are sure that you cannot use more than a single monitor in Quad SLI.
