I've been debating whether to get the 15 inch macbook pro retina with the integrated GPU or not. I'm not sure how well the gtx 750 is for gaming and if it was worth the extra money. But when I maxed out both models, the price was the same. The only difference was that one had the 750 and the other had just the iris pro. Both were $3300. That is with the 2.6 quad core i7, 16gb RAM and 1tb ssd. I didn't compare the prices of lower specc'd models because I'm planning on getting a fully loaded 15". So, is there something I'm missing here? why are they the same price when maxed out?
