I'm thinking of getting an Asus GTX 780 3GB DirectCu II OC. I heard that when you overclock this card you can get a performance very close to the Titan. So I don't think I will have any problems running Battlefield 4 (Ultra settings) on a 120Hz 1080p monitor with this one.
Btw: I'm planning to add another one next year to SLI them. Will there be any problems since this card has custom cooling?
Asus GTX 780 OCed is good card for upcoming games like BF4. You could also try AMD R9 series as well. Be sure your CPU will not bottleneck this GPUs, because you didn't specify your PC other relevant specs.

Go for the 780.A 3GB version good for multi monitors.It's based on the GK 110 core slightly less shaders than the titan,but the 780 is worth every buck.If you have the budget of course I dont needed to say about the budget as u mentioned in the first thread but if you listen to me.If you plan on single 1080p 780 is a overkill.But on resolutions such as 5760x1080p 780 is a perfect match
