OK, so if I use the 3840x2160 on the current settings as suggested by NVidia the game runs terribly. It's choppy and slow. However, if I dial back the resolution setting just a bit it looks amazing. Could this be an issue with this monitor I have or maybe just a single card is a tad under powered? And if it's the single card, going back to my original question, could OC'ing this card make a difference in how the game plays?
