Will 2X 5K Monitors decrease performance?

Greetings,
I read somewhere a long time ago (When the GTX 970 was new) that a higher resolution screen would decrease the performance of the GPU. In addition to the server I'm building (I'm an Indy Dev.), I am building a couple content creation PCs. In one of them, I am going to use 128 GB's of DDR4 3200MHz RAM, an i7-6950X CPU, and 2 Titan X (Pascal) GPU's in SLI configuration. I am going to connect to it, 2X 5120 x 2880 Monitors, and 1X 1920 x 1080 touch screen monitor. Will these monitors decrease the performance of the Titans at all? If so, do I need to use 1 5K monitor and the touch screen, or just 1 5K monitor?

Also, the TITAN X's Spec page says the Maximum Digital Resolution supported is 7680x4320 @60Hz. Does that mean the collective resolution of multiple screens or the max resolution of 2 or 3 screens?.

Thank you for your time.

It's not that the resolution will decrease performance, it's that the higher resolution is a lot more pixels to push. Something like CS:GO will still run most likely at hundreds of frames per second, but something more demanding like The Witcher 3 will see 40 - 50 frames. A pair of Titan X(P)s should be able to run a pair of 5k monitors, but it's just gonna be enough to push them to game on, content creation and gaming on one will be doable. The 1080p touch won't add all that much to the amount of pixels rendered, but definitely something to keep in mind that you can shut off if performance isn't that great.

As far as the resolution, I think you can set up each 5k monitor as it's own screen, but you won't be able to span them, so it...

I took a look and found this post. I believe the max supported resolution is per screen:
http://www.tomshardware.com/forum/id-1657778/triple-monitors-max-resolution-display-multiple-displays.html

so you should be good. I guess the titan x supports 7k monitors?


as for the decreasing performance, im not sure what you mean. You will see lower performance on a 5k monitor than a 1080p but that is because you are rendering more pixels per frame. Its not like it will hurt your gpu's, they will just have to work a bit harder to render the same image in the higher resolution

also i like jossrik's advice. id call nvidia support . if youre buying 2 of their top GPU's, i cant see them not helping you with what you need

As far as the resolution, I think you can set up each 5k monitor as it's own screen, but you won't be able to span them, so it won't look like one monitor on the pair. The max resolution is for multiple monitors set up as one desktop. To be sure, give Nvidia a heads up and see what they say, or more hopefully, some one from there will see this, or some one from here who knows for sure and they can chime in.
