    Hi guys,

    I'm receiving my 27" iMac tomorrow and I was wondering what kind of performances I should expect from the GTX 685MX.

    Since my Windows desktop has a GTX 570, I was wondering how will the GTX 685MX performs comparing to it.

    Thanks!

    gtx685mx? - guess you mean the 680mx

    check here as soon as benchmarks will be available.

    and keep in mind that the iMac uses a mobile GPU!

    The 6xx GPUs are based on a new architecture different from the GTX570.

    There are many differences.

    See my pictures.

    Picture 1 is GTX680MX
    Picture 2 is GTX570

    sry for the german pictures ^^
