Still decent FPS even for a 690/SLI680. 4K is out of my budget for a while though till it becomes more standard.

I don't know why they are claiming "4k resolution" in all the games tested...
Some of the games shown much small resolution in the configuration screenshots:
Battlefield 3 : 1920 x 1200 @ 59.86 Hz
Crysis 3: No configuration screenshot posted.
Dirt 3 :  1920 x 1200 @ 60 Hz
Farcry 3 : 2560 x 1440
Skyrim : 1920 x 1200 (Shows a GTX560 Ti as graphics adapter...) 
Sleeping Dogs: No configuration screenshot posted.
 
For me, this "review" has a lot of typos or it is fake...

The 30hz would give me some serious headaches. I can only stand 60hz for an hour or 2 at the most.

well the 30hz @ 3840x2160 could be cause current video cards can only handle 2560x1600 @ 60hz, basicly the TV technology is ahead of what current video cards can support. The picture I posted above, they had to disable vsync to get that 43fps on fraps.

AMD and Nvidia will have to figure out how to get that new resolution to run more efficently

Incorrect. Current GPUs can process 16k x 16k resolution if you understand how to interprit dxcaps.exe data on current generation Nvidia and AMD cards. DisplayPort 1.2 is perfectly capable of pushing UHD at 60hz+ and there is zero limitation on the GPU for that type of pixel processing. The issue is the HDMI 1.4a port that TV uses, not the video card. HDMI 1.4a is deficient in many ways compared to DisplayPort 1.2 -- primarily in bandwidth limitations. It's limited to 30hz because HDMI 1.4a at UHD only has the maximum bandwidth of 30hz. It's a whole different story with DisplayPort 1.2.

Digital S3D movies in theaters are often 144hz and/or use two projectors -- 1 per eye with a polarized filter on the lens.

Though the digital projectors are refreshing at 96Hz or 144Hz, the film content is still just 24FPS. Unless it's the Hobbit which in that case would be 48FPS.

I don't think it's necessarily the resolution.  Most theaters, even if they have 4K projectors installed are still just playing 2K DCPs.
 
Newer theater projectors are just getting better in general.

I seriously can't wait for this to become mainstream... 32" 4K screen = perfect.

That too

with me getting a GTX 770 later, I'm sure it will be way overkill for my 1920x1080 

There was a time where 3-way 8800GTX was considered overkill for 1920x1200, but the performance equivalency to those graphics cards is a single GTX560-- not overkill anymore as the games themselves have changed.  
 
Remember, time doesn't stop once you make an upgrade; don't be too concerned about overkill unless you don't plan on getting those upcoming games that will require you to get another GTX770 (or upgrade to the equivalent single-GPU) to maintain your preferences at 1920x1080.

At least we are turning in the right direction.
 
Soon they will be able to release them with correct connections and be 60-120hz+ capable.
 
At 30hz, though, this would make a wonderful work monitor I would think. :)
