imac 27" pixelated screen, help!

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?

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