Did you not even read the post that you had quoted? It said:
"I think brick and mortar retailers should actually hook up high-end gaming rigs to their 4K demo units, and show off a high-end PC game like Crysis 2 running in 4K resolution. I think it would sell vastly more 4K displays to the gamer crowd, and I think there are more gamers that would consider spending the money, than people wanting to see the scant little 4K video content that will be available."
There was nothing about your definition of what "full 4K gaming" is, or anything else.
If you are using it as a demonstration of what 4K offers for gaming, which one would assume means relative to what console gaming is like (as that's the "average" gamer) then 4K at 30Hz on a PC is more than enough to show a significant improvement, as the consoles struggle to run games at
And it's clear that you are not a PC gamer. Yes, current cards will not run games "maxed out" at 4K while keeping an average of 60fps.
But any PC gamer knows that games are built with future generations of graphics cards in mind. Running most games on their "ultra" setting is generally not feasible at the time of their release - they include many effects which are more technically correct but only marginally better looking.
These settings are used in benchmarks, because it stresses the cards more and does a better job showing off the differences between them, and it means the tests are GPU-bound and not CPU-bound.
The tests you linked to show that a single Titan is capable of running those games at ridiculous settings, above 30fps.
A GTX 780 has essentially the same performance as a Titan for half the price. ($500) The Titan is really a card for people that do rendering/compute, but don't want to pay for a Quadro card. It's not aimed towards gamers.
As an in-store demo for 4K, this would be more than sufficient.
