Alright, so me and my friend are both buying laptops soon and I was wondering which of our video cards were better. His laptop comes with a AMD Radeon HD 7730M, and mine comes with a NVIDIA GeForce GT 650M. Now as a default, I'm going to assume that his, the Radeon, would work better just because I find that AMD's video cards are generally better, but does anyone actually know? Any help is appreciated. Thanks.
