Mate that looks like an overheat issue to me in which case you CAN damage your card but its not CoD that done it imo..
you said you've played 200-300hours with no problems? don't you think its a bit strange then that all of a sudden CoD decides to break it for you?
Games don't break hardware, and if it was maxing out your gfx card then you would know long before and would adjust settings appropriately.
This is either a malfunction hardware wise or driver bugs either way associated with heat I would say
