I'm with Khaine on that, It depends. All I have right now on my laptop is base game. That's all it will handle. Even with a cooling pad, when I play it, specially now that it's summer, I get about an hour of play-time before I have to get out of the game. But of course, save it before I do.
If I'm going to play for another hour or so, I'll restart. But if not I'll just go do whatever else and then reboot later in the day.
