I have a monitor with resolution of 2560x1440. I want to be able to play games like BF4, GTA5, Crisis 3, Metro LL, etc. on ultra. People were saying that a single GTX780 cannot keep the frame rate above 60 in this resolution. So I will either go with Dual GTX780 or Single GTX780ti (might try any get another one for christmas). So what do you think.
