Looking for a 4K GPU

[Mondo]

I'm looking for a gpu that will power a 4k screen as well as a 1080 secondary screen. This is for a work station that'll be used for some Photoshop and other stuff. Was thinking team green was the way to go, maybe a 750ti or 960. This will NOT be used for any gaming. Any suggestions?

Why not just stick with your current 780? If you absolutely need a new GPU for some reason, between the two in the OP, I would go for the 960. Though the 750ti can output both 4k and 1080p at the same time as well.

Which version of Photoshop? If it's the newest one i'd say AMD. They support OpenCL better and AMD cards perform better than their Nvidia equivalent. I'd say a 280 outta do it. Can get those for hardly anymore than a 750ti. Though I think the 960 performs a little better iirc. Also more money. You can get a 280x/285 for 960 money and they probably perform better.

With that said the 780 is far more than you'd really need.
