For those asking if the gaming on the Retina is smooth on extremely high settings, the answer is YES. Just played Tomb Raider (2013) on 1920 x 1080 with everything maxed. Not only is it smooth, but the graphics are OUTSTANDING, and it didn't even stutter. SimCity (2013) also plays EXTREMELY well on maxed out resolution and settings. The entire process was just so fast and packed full with amazing animation. Couldn't be more impressed and blown away by the performance of these games on this Retina MacBook Pro. I know these were just two examples, but if you game, don't even hesitate-just buy the Retina. Played on a 2013 15" Retina MacBook Pro - 2.4GHz - 256GB - 8GB.
