I'm certain that you can run 6x2560x1080 of a fury x, it would just require 2 (although I'd recommend 3) MST HUBs. Eyefinity doesn't like when you mix connection types, so going full display port would be most recommended. It get rid of a tearing issue due to timings being different on DP versus DVI/HDMI.


I just realized you didn't say ULTRA-widescreen, what's the resolution of the monitors? This is more important than anything.



Currently using nvidia cards but if i can run 6 ultrawide 34" 3440*1440 monitors with amd i'll switch. I don't play that many games but if play it will be off one of the monitors. My plan is to use all monitors for separate windows so i don't need it to be a huge resolution like 15k*1440p.

I've read so many conflicted opinions on eyefinity so i don't really have a clear idea if this will work or not. Some say you need 2 cards and others say you can do it with 1 but then there is not enough bandwidth for these resolutions.

Well, you would need to run 2 monitors off one DisplayPort. And there are 3 of them. Using a bandwidth calculator, you get this result for 2x3440x1440:

Code:
6880 px, 1440 px, 60 Hz, 24 bit, aspect ratio 4.78, 14.27 Gbit/s.

15.01 Gbit/s, CVT-R, 18.77 Gbit/s TMDS, Pixelclock 625.520 MHz.
14.84 Gbit/s, CVT-R2, 18.55 Gbit/s TMDS, Pixelclock 618.412 MHz.


And DP 1.2a has a max bandwidth of 17.28 Gbit/s.

So... Maybe. I haven't found any post online about someone using 2 off a DP using MST. Some of the 3440x1440 monitors have MST built in actually.

Is that 17.28 gbit/s bandwidth shared for all dp ports on the card? or is it per dp port? If its per dp port then i think i can use two mst and get 4 monitors running that way. What do you think?

It's per port, so I think it's possible.

The AMD fury has 3 Dispayports. And you would need 2 of that card in Crossfire if you want to play games in that resolution. Vram might still be at its limit with 4gb!

If you don't want to use Eyefinity to maximize windows over all 6 Monitors you could use 2 cards and connect 3Monitors to each. Or take a look at the Firepro series with 6x miniDP it you dont intend to game at all.

Gaming Eyefinity 5 Unreleased
ASUS STRIX R9 Fury DC3 4GB [1xDL-DVI, 1xHDMI(1.4), 3xDP(1.2)] - Finally a high end single GPU card with at least 5 outputs. Although I'd rather it have another DP rather than an HDMI and I'd also rather it be a Fury X.

Both GIGABYTE R9 390 parts say 4 monitors supported in their specs, not 5.

I can see that, but it doesn't make sense. All AMD cards these days support up to 6 video streams on one card (even if they don't have the ports). That's probably an error.
