Apple iMac MK462LL/A 27-Inch Retina 5K Desktop

New at the Apple store for only $50 more (http://www.apple.com/shop/buy-mac/imac/27-inch-imac-with-retina-5k-display). Unimpressive w00t IMO.

Does this thing really have 1TB graphics memory? That seems unrealistically high.

Edit: On further inspection, the description actually lists it as 2GB. The spec sheet just must be typed wrong.
