XGI Technology is still in business, but what has happened to
them? We once saw hope in them for providing discrete graphics
processors to take on the NVIDIA and ATI duopoly, but they have since
discontinued their Volari 8 series. While they're no longer producing
these desktop chips, they remain an active player in the server and
embedded graphics industry -- accompanied by their open-source driver.
