I have three monitors and I would like to know what would be better for 6000x1080, two XFX 280x's or a single 6gb EVGA 780? I'm not worried about the price difference; they're close enough to the same for me. I just need to know which would be better for performance assuming there is no micro-stuttering.

I have a single 270x and get around 40fps in GW2. Do you think 60 fps is obtainable with either of these setups?

Specs:
CPU: AMD FX 8350
RAM: 2x8GB Trident X 1600mhz cas 7
Mobo: Asrock 990fx killer
SSD: Samsung 840 EVO 250GB
PSU: Corsair AX760
