Unfortunately we are unable to provide specific FPS information as that is dependent on your in game settings. This system can run both those games well, so you can expect to see smooth gameplay!

Yes this PC would work with a 240hz monitor! Depending on what games you will be playing, you could be hitting 240 FPS. It is up to you whether you think it would be more worth it to have a 144 or 240 hz screen!
