I'm currently in the market to pick up a MacBook Pro, but the inability to have a dGPU on the base model was a big curve ball from Apple for me. I've looked at the specs comparing the 1 GB GT 650M and the Iris Pro graphics and the gaming screenshots look pretty similar. But can anyone attest to the real world usage between the two? Will I get about equal gaming performance with Iris Pro as I would on the last gen model with dedicated graphics? Are they both about the same performance for video production? Any information would be helpful! Thanks!
