The only 4k display that can accept a 4k feed from a pc so far is the eizo £35k one... the 4k TV's only have hdmi so pointless for gaming
Here is a video of Battlefield 3 played @ 4k on a 680.
If you have a 4k screen you can watch the video in 4k.
Also remember 4k is only +30% pixel count above people with 3 x 1080p displays so SLI 680/670s should be able to play most games pretty much maxed out @ 4k.
Aren't the AMD 7 series ready for 4K via HDMI?
^^ Very true but I am pretty sure it is a couple of years away before those monitors/TV's become mainstream and affordable.

I think it may be as long as 10 years before we see mainstream TVs using 4k. The TV broadcasting companies are only just getting to grips with normal HD.
No, in 10 years 8k will be roughly where 4k was a year ago.
I give 4k another 2 years & it'll be hitting the higher end of consumer affordability. Another year after that and we'll see £800 sets.
I read somewhere that the PS4 will support 4k, that alone should boost its popularity.
