I was choosing my 15" Macbook Pro, and I am getting the 2.3 GHz, 8GB version. However, I was concerned about the impact on performance the 36% more pixels from the 1440x900 to the 1680x1050 would have on gaming performance on games such as Dead Space 2, Bad Company 2 (Vietnam+Original), Black Ops, and Fallout New Vegas. Ideas? The reason I and so picky about this is that I prefer native resolution while gaming.
