Hi, I have a ASUS motherboard model P5W DH Delux, I am trying to buy the fastest graphics card that is compatible to the board.
Can any one help suggest a really fast card? One Gb is what I would like. I have been looking at the GeForce 7950 GX2 but cannot find out if it is compatible. Help anyone?
