I was looking at benchmarks for both of them, since I don't know which 15in Pro I should get. These benchmarks kind of confused me, since the only GPU intensive game I am going to play is BF4. 750m Benchmark http://www.notebookcheck.net/NVIDIA-GeForce-GT-750M.90245.0.html Iris Pro 5200 Benchmark http://www.notebookcheck.net/Intel-Iris-Pro-Graphics-5200.90965.0.html Overall, the benchmarks show that the game runs both the GPUs at the same FPS. Shouldn't one of them be more or less of the other? Thanks.
