    Hello there lads, help needed.

    After a couple of hours of Assasins Creed -and most likely due to overheat- i got these pixels everywhere. I uploaded a video on youtube, have a look here

    Is anyone familiar with this?

    System specs:
    imac27" Mid 2010
    intel core i7 2.93
    16gb 1333DDR3
    ATI Radeon HD 5750 1GB

    Hope you have AppleCare. That looks like a GPU crapping out.
