What graphics card will best handle 3 monitors in 4K?

Question

Iron

The task is to decide on the video card.
Video card requirements:
ability to work in 4k resolution with 3 monitors (27 inches).
tasks from "screen saver" to "heavy" graphics processing and "cool" games.
(corn and other titanfall and battlefield 4)
my candidates:
nVidia Titan X or two such
AMD Radeon R9 390 X or two such
if there are other candidates more worthy, I will be glad to know about them.

Answer 1

in games, not a single card can cope, no titans will help if - there is no optimization for them, the maximum that you get on one monitor in 4k is 30 fps

Answer 2

Well, you can't do without CrossFire or Sli, either of the two options is only in the 2nd version.

Answer 3

If you can’t, but really want to, then you can . For 4k, memory bandwidth is super-critical, because shaders can always be turned off, and geometry can be simplified. But for 4k, you need at least 20 gigabits just to display the pixels on the screen. But besides this, you need to load the textures, and calculate, and put again, and several shaders. To tell the truth, the low segment is artificially limited in performance - memory is an easily adjustable throat, practically impossible to overcome, because it is chasing terribly.
Many have already said about SLI - support from games is required, and its quality leaves much to be desired. But here is a super-top and performance is needed just the maximum possible. In extreme cases, one card can be sent to consider physics. Also, 1080Ti may also be nothing like that, well, the cost is an order of magnitude cheaper, of course. According to the characteristics of the 1080, it is approximately the same as the Titan.

Answer 4

But what about the GTX1080 with pascal technology?
2 such cards in SLI and everything will be OK.
Indicators for monitors >1 are superior to titanium X
Of course, if you are not in a hurry and are not currently sitting on the cards of the previous generation)))
