Which graphics card(s?) for 6 x high res monitors, not gaming

[Aquinus]

For that price, better off going with two RX 560s.

RX 560 = 3 displays
RX 570 = 5 displays
RX 580 = 5 displays

Can't find anything on Vega.

Yeah, the price isn't great but, the price might be worth it for a single slot card with 6 mDP outputs. Anyone looking at this is not planning on doing any gaming and cares more about how much space it takes up and how many monitor outputs can be used. Unfortunately, the only way to get a single slot card and 6 output is with 6x mDP outputs and options for those is very limited. Looking only turned up this card, a more expensive 7870 (not single slot either,) and some very expensive FirePro cards which themselves aren't single slot either, except for one that's basically exactly like the 7750 there.

200 USD might be worth it for 6 monitors and a single slot card given the OP's requirements.

Reason why two cards is better than one is, for example, video playback on multiple screens. Each video decoding taxes the GPU so the more grunt behind it, the better it is able to keep up.

If power consumption and heat are a concern, better off with having two NVIDIA cards. NVIDIA has historically drawn less power driving multiple monitors.

But, that's not what he's going to be using this for. He described what he wants to use this for:

In a given session I might have:
2 open browser windows/tabs with documentation for what I am working on
1 code editor
1 database interface
1 slack/skype window
1 Postman app to test API calls
1 project management thing (Trello)
1 browser to search for error messages, stackoverflow posts etc

This is for productivity and GCN 1.0 is capable of doing decent playback. Even VLIW5 with my 6870s could handle most formats I was using but, it's enough for 1080p and anything else isn't exactly what the OP is looking for. So while I agree that multiple GPUs are good for that purpose, it's not something I think the OP is looking for. This about displaying information more than anything else.

he has if you read the OP post, 6x 1440p monitors not 1080p

You missed the point then because the OP said nothing about watching videos at 1440p. In fact the OP said absolutely nothing about watching videos in the first place but, it's not unlikely that the 7750 could decode 1440p video in certain situations. The OP did a fairly good job making it clear that the goal is to use this machine for productivity purposes and never once mentioned video but did mention that gaming was not a factor so, given that and the quote below, I think you can say with confidence that video performance at his native resolution isn't a cocern that is paramount.

You may have missed it but, the OP did say what the was going to use this for:

1 code editor
1 database interface

1 browser to search for error messages, stackoverflow posts etc

The OP also made it very clear what his goal was. It's even in large, bold, text... preceded by what it's not for.

What graphics card(s?) should I go for, to feed the 6 monitors at this resolution?

It will not be used for gaming at all, so game performance is irrelevant.

What you're seeing is a dev who doesn't want to switch between windows. Honestly, I can't really blame him. I got the three 1080ps under the same mentality.

I have had 4K monitors. Did not care for it. I much prefer this.

Main reasons:
- I really want the area, square centimeters, not just the pixels
- Each screen to me is a workspace. This one has documentation, skype and slack run on this one, here is the code editor, here is a browser etc etc.

For gaming, this would not be optimal and the bezels might distract you. For my use, this is way better.

well that does make sense, but windows can be separated into workspaces in software (probably easier in linux with certain window managers), the pixel count is specific to fixed size user interface elements like the browser addressbar, taskbar, etc

i guess screen size would limit the choices to televisions or overpriced industrial, also makes me wonder about the structural integrity of a single large screen with its weight
