Not to necro an old thread.
My setup is one 780 ti. I am waiting for the second
The wife has dual 290 that we will be water cooling.
We have the sony xbr 65 4k that got updated to 4k hdmi 60hz. I am going to see if I can make it work with our computers. If not when the dell 28in 4k comes out I May pick that up..
