Hi, does anyone have this in their MBP if so can you tell me how good it is compared to the NVIDIA 8600? Can you play cod 4 at a decent frame rate? Is it still fast and all? I am looking at the refurb page and see that a MBP has it for 1299 so that seems not bad. Thanks, ChrisN EDIT* Just checked the store and it is gone, pretty fast but still if anyone has it then can you just answer.
