I bought a macbook pro with retina display(with maximum settings availabe) a month ago and tested some intensive games such as skyrim and battlefield 3. The frame rate was fairly endurable for me, but what I could not tolerate was its annoying noise which started once I launched games. I do know apple did a lot of work do deal with noise on MBPr, but it kept me annoyed during the play. I would like to ask Imac users if your imacs make as much noise as MBPr when playing high-spec requiring games. Considering the thinness of newly reported imac, how do you think apple took care of noise? especially with GTX675mx and 680?
