I've read a lot of things over the internet saying that Civ fried their GPU and stuff but that was around the time it was released which was 6 years ago i'm new to Civ and everything works fine but im only asking this to be safe. I've got a MSi GTX 970 Twin Frozr V and its one of those cards that the fans only spin up when it gets to a certain temperature and whilst playing civ the fans do start to spin up not fast but they do spin a little i also have V-Sync enabled if u need anymore info about my system etc then feel free to ask.
