I'm going to be getting a new pc soon, and I just wanted to know whether a single GTX 780 ti could run very graphics intensive games on a triple monitor setup at an average of 60 fps, or would two GTX 780s in SLI be a better option? I know the GTX 780s would be better but if the GTX 780 ti can run well, I would not want to be wasting any extra money. Thanks in advace c:
