I have the 2008 15" 2.53 GHz, 512 vRAM 9600M GT Macbook Pro. A guy at the Best Buy store told me (when I was buying more RAM) that my model has an NVIDIA nForce motherboard. I doubt this is true, but can anyone confirm this?
I believe Foxxconn does the actual manufacturing (like many other OEMs) of the board. Though there are rumblings that Gigabyte may enter the fray to provide Apple with USB 3.0.
