I've been using a refurbished 2010 15" MBP for the last few years now, and I love the machine. It still gets me through day to day for now, but there are lots of bugs with the dedicated graphics switching and I have a growing need for mobility and battery life and I use the machine more and more for school. I've been looking at the new 13" Retina Pro, and the reviews seem very promising. I'm having a hard time finding decent information on graphics performance on the new machines, and I'm curious what it would be like dropping down to a smaller (but better) screen. I know the 330m in my 2010 isn't the best performer, but it gets my gaming needs taken care of. I'm curious how the Iris graphics will stack against that. I occasionally play Dota 2 and a few other indie games, but I generally stay away from AAA titles (I have an Xbox if I really want to play something intense). As for the screen, I spend 80% of my time writing code (getting into upper division Computer Science courses) and that's really what I need the computer for. I have the lower res 1440 x 900 on my 15" now, and I do use a 1080p external monitor at my desk. I was planning on using the retina display in at least 1440 x 900 mode, if not higher. Has anyone made the switch from a larger screen down to a smaller retina and have any input there? Yes, I am aware of the image retention problems and such, though I'm not too concerned or worried. I'm planning on either the 16/256 BTO options, but I haven't decided on a CPU upgrade yet.
