Why would you need 7680x4320 at 60Hz?  That's 8K.  3 4K monitors is less
than that.  Or is it that you want to run three 3K screens side by side?
I found a claim that the 980Ti at least was listed as supporting
11520x2160 to run three 4K screens so it would seem at least nvidia
cards that are current can do it.  I think you had to go to the 10
series to get HDMI 2.0b though, the 900 series probably required using
displayport to do it.
