First off hello everyone. My problem is this: I am running two xfx 6950's flashed to 6970's. They are the 2gb edition and I am trying to install a Nvidia geforce 6 series card as a physics adapter. I have downloaded the physics mod but my computer will NOT recognize the card at all. I am running an MSI big bang x power 1366 with an I7 920 overclocked to 4.03 GHZ with 24gb of ram. I am lost at this point anyone know my issue or any help?
