Old or new card for a 4K Monitor.

[embalse]

At present I have a Gainward GeForce GTX 680 Phantom 4GB GPU. I am about to buy a 4K monitor. It's for CAD work, no games.

My question is...
Would I be better off buying another Gainward GTX 680 (Second hand) for SLI or selling the GTX 680 I have and buying a new card (or two) for a 4K monitor.

It would save me a lot of money just getting a secondhand GTX 680, but maybe that's a false economy.

I don't know much about CAD but if it uses a lot of VRAM then something like this may be better.

Or if you want something a bit quieter

Thanks for the suggestions. . Sorry I should have pointed out its for a Asus Z10PE-D8 WS Intel X99 board.

Clearly you have the money, so go with 2 of the 8gb 290s mentioned above... go on, you know you want too they will beast anything you put infront of it

If it's purely for CAD, and no gaming, you're better going for an ISV certified card, such as a FirePro or Quadro.

I use Modo/Lightwave/Zbrush which use the use the CPU for rendering and don't take advantage of the GPU, so a quadro would be overkill for those apps IMO, plus a lot more expensive.

If the software you use doesn't use the GPU at all then just keep the 680, as no newer GPU will make any difference to your cad programme.
If you are not gaming, or using a GPU's compute functionality then you don't need to go SLI at all, you are just using the GPU to display the image.

The frame buffer actually needed to display an image at 3840x2160 is about 32MB so even the most basic of modern cards could do it.

Thanks for the clarification. My concern was for the monitor not the CAD work. So it's good to know my 680 can last a bit longer!!
