I've toasted two laptop monitors because of trying to play too many high-needs video games on them. Both of the monitors theoretically were good enough for the games by specs, but both of them burnt out within two years of when I bought them (admitedly, they were both a couple years old when I purchased them). With the first laptop, I just thought it was an age thing and didn't think enough of it, but with the second one, I realized the sad pattern. Now, I play my games with an external fan running, blowing cool air under the laptop, with the laptop on a stand to increase airflow. (I'd stick to playing games on desktops, but I'm living abroad at the moment, and a desktop takes up too much room in the suitcases)
All this being said, it seems like each new generation of laptop video card is more powerful, but I would just like to know of a mid-range card that ran really cool. That would help me much more than power.
