Hi! I have a MacBook Pro 2.53GHz 15" model running 64-bit Windows 7 via bootcamp. I've been reading that the MacBook Pro has a GeForce 9600M discrete graphics card, but Windows only sees the GeForce 9400M integrated chip. How do I know if it has the 9600M? How do I get Windows to use it? Can it use both in SLI?
