I'm in the same boat as tony, As I had a 7950 GTX previously, and I got stuck with a Single 8700GT 256M.
Dell keeps flip-flopping between refusing to give me ANY Video Card replacement as it's an upgrade, and saying the 8800M GTX I deserve (Noted by SEVERAL Chat techs, and LOGGED.) is out of stock with no data on when it should return to being instock.
Welcome to hell. Yours is gone.
