I played in WoW battlegrounds on max settings. It froze every 5-10 minutes.
I played WoW on "medium" settings and set my max fps to 30. It improved, but froze every 20 minutes.
There's also a dead pixel in the upper right hand corner, next to the Macintosh HD icon, which is an area I click on daily, obviously.
By "freeze" I mean the cursor stops. The screen freezes. And the sound.... it's a rhythmic sound loop that repeats what I've heard directly before the freeze.
