Thanks for the advice Ink, I just downloaded the game and was playing around with it for a few hours. Considering that I felt I barely meet your min system requirements I was surprised that it ran fine when I chose "good" graphics quality, and 1920 x 1080 resolution.
I didn't monitor temperatures (I need to find a way I trust to do that, speedfan has been giving me some really strange readings in the past few years...) but my computer was quieter than when I ran GTAV or Crysis recently (I think that was mostly due to GPU fan) and according to the task manager (which I had open in a 2nd monitor) my CPU barely broke a sweat, it was never above 30%, though that may be because the game was only using one of its four cores.
