Holy shit, I haven't jizzed myself over new technology for some time, but this sounds incredibly promising...
Just need them to crank out 1440p IPS versions, seems they will be crap TN 1080p panels to start...

"Vertical synchonization, or V-sync, is a very old solution to the tearing problem. Enabling V-sync essentially tells the video card to try to match the screen's refresh, eliminating tearing entirely. The downside is that, if your video card cannot keep up and the frame rate dips below 60 FPS (on a 60 Hz display), effective FPS bounces back and forth among integer multiples of the screen's refresh rate (so, 60, 30, 20, 15 FPS, and so on), which in turn causes perceived stuttering.
When frame rate drops below refresh, you encounter stuttering with V-sync on
Furthermore, because it forces the video card to wait and sometimes relies on a third back buffer, V-sync can introduce additional input lag in the chain. Thus, V-sync can be both a blessing and a curse, trading one compromise for another set of compromises. An informal survey around the office suggests that most gamers keep V-sync off as a general rule, turning it on only when the tearing artifacts become unbearable.
Getting Creative: Nvidia Introduces G-Sync
With the launch of its GeForce GTX 680, Nvidia enabled a driver mode called Adaptive V-sync, which attempted to mitigate the issues with V-sync by turning it on at frame rates above the monitor's refresh rate, and then quickly switching it off if instantaneous performance dropped below the refresh rate. Although this technology did its job well, it was really more of a workaround and did not prevent tearing when the framerate dropped below the display's refresh.
The introduction of G-Sync is much more interesting. Nvidia is basically showing that, instead of forcing video cards to display games on monitors with a fixed refresh, we can make the latest screens work at variable rates.
The GPU's frame rate determines the monitor's refresh, eliminating the artifacts of V-sync on or off
DisplayPort’s packet-based data transfer mechanism provided a window of opportunity. By using variable blanking intervals in the DisplayPort video signal, and replacing a monitor scaler with a module that works with a variable blanking signal, an LCD can be driven at a variable refresh rate aligned to whichever frame rate the video card is putting out (up to the screen's refresh rate limit, of course). In practice, Nvidia is taking a creative approach in leveraging specific capabilities enabled by DisplayPort, taking the opportunity to kill two birds with one stone."
-------------------- Everything is better than it was the last time. I'm good. If we could look into each others hearts, and understand the unique challenges each of us faces, I think we would treat each other much more gently, with more love, patience, tolerance, and care. It takes a lot of courage to go out there and radiate your essence. I know you scared, you should ask us if we scared too. If you was there, and we just knew you cared too.

For sure, though 4k is def. another game changer on the extreme end...
I've read Dell will be pushing out sub $1,000 4k panels in early '14... seems like you'd want nothing much less than a Titan or a heavy duty SLI rig to reasonably game at such a beastly resolution, though the Titan has performed quite respectably at 4k from what benchmarks I've seen...
I'm not sure how I feel about the G-sync being closed NVIDIA ecosystem tech, and I wonder what will happen should AMD role out their own solution... All I know is that I'm super picky about displays, and if my dream display had AMD's tech, I'd be wicked fuckin' pissed, 'cuz that ain't gonna happen. Would rather just see one open source tech as a universal standard for all monitors that all modern GPUs supported...
