I'm looking at two laptops that I was thinking of getting for 3D animation work. One has an nVidia GeForce 9600, which the nVidia site lists as a Performance Card, and the other has a G105M, which is as far as I know, a newer card from a more modern line of cards, but categorized only as a Mainstream, not Performance card. The configurations of the two laptops are pretty similar. Any advice would be helpful.
