Hey,

I have currently Gtx 680s in SLI both 4GB cards, I currently have asus 2560 1440 display and want to upgrade to a 4K moniter for gaming, work and movies. Can I even buy one currently like 27inch or 30inch ( My budget is around £9,000-10,000 I have saved for this) and as well I hear HDMIs currently only output 30FPS on 4k and what about DVI cables do those work with 4K and at what FPS?
 
Solution
Far as I can tell, the 680's cant support a 4K (3840x2160) resolution regardless of which connection you use.
A Titan can support a resolution high than 4K, so I imagine your good to go if you get one.

Though I have a similar opinion to the others, 4K displays are pretty expensive as is and there isn't much content to take advantage of it (or even GPU power unless your willing to drop a ton of cash). However that does seem to be changing fairly quickly, if the trend on 4K TV's continues, 4K monitors are going to be dropping in price very quickly. I would wait on getting one.
From what I gather with my research the 680 does not support a single 4K monitor. Part of the problem of being the first on the block to own them is not too many mainstream solutions exist.

The GTX 680 is listed as max resolution of 2560 x 1600.

From the GEO Force Forum
Points:

- GTX680 supports 2560x1600 which is 4,096,000 pixels

- so that's 4 Mega-pixels (4 million pixels) and NOT the 4K standard

- HDMI output probably supports both the PC and HDTV standards

- PC-HDMI should support 2560x1600 (i.e. HDMI->DVI)

- HDTV-HDMI should support 1920x1080 (i.e. 1080p60_NTSC

Maybe as it becomes more mainstream they will be able to do it with a software fix because 2 680's should be able to handle it.

4K isn't supported over DVI. You can use HDMI or DisplayPort... but for a consumer, it's hardly worth that investment for a 4K display today, especially with little content available at that resolution.

There are very few 4K solutions available, especially in the 30"' PC display size range. One you can look for is the Sharp PN-K321

Your GPU solution is too weak for 4K display. You'd be getting pretty low FPS on max settings (no antialiasing either). It kind of defeats the purpose as well, since you're going for a high-end experience with 4K, which is contradicted by the fact that you'll be playing with lower graphics quality. I also have to ask, why in the world would you consider 4K on a 30" monitor?! The pixel density for 2560x1600 is very high as it is. You wouldn't notice a difference with 4K unless you literally have your eyes an inch or two from the monitor.

If you really need 4K, I would recommend a larger display and you will definitely need to upgrade your GPU solution to 3-4 GTX Titans if you actually want to play with adequate settings.

30" 2560x1600 is not a high pixel density at all. Not everyone plays the latest games or just watches movies with their PCs. I run multiple 2560x1600 displays per computer, and still run out of space for my workflow. Most applications have horrible bloated eye-candy UIs with very little information density and the only way to combat that is through more resolution. It's quite a shame MS introduced desktop compositing with Vista but didn't go the minor extra step to add window scaling.
 


A higher resolution reduces the need for higher levels of Anti-Aliasing, at a 4K resolution and the pixel density your going on about, I imagine it wouldn't even make a visual difference.

 
They were able to do it here on the 680. I believe the Nvidia spec's is just old because it was the first of the 600 series: http://www.pcper.com/reviews/Graphics-Cards/Frame-Rating-High-End-GPUs-Benchmarked-4K-Resolutions

They have a preview of them unboxing and hooking it up in a video as well. They just plugged it into their 680's and it worked with nothing special needing to be done other than choosing the resolution in the Windows screen resolution dialog.

Surprisingly, they had decent settings, but at 30hz, it wouldn't be ideal either. At least not up close.
