The XG Station connects to any notebook’s ExpressCard slot and provides a PCI Express x16 slot for graphics cards.

ASUS launched the default XG Station with an NVIDIA 7900GS powered graphics card.
The XG Station is powered externally. A separate power brick plugs directly into the adaptor.
An integrated LCD display and control also grace the XG Station. The display is customizable and can display information such as frame rate, fan speed, GPU temperature and more while the control knob can change various settings of the XG Station such as the core and memory clocks.
Expect ASUS to release the XG Station in Q2'07 this year. Pricing of the XG Station is unknown at the moment.
The XG Station adaptor only interfaces with ExpressCard interfaces at the moment, but will work with with PCIe ExpressCard interfaces installed in a desktop PC.
