Cheap GPU for 6 monitors ?

[dungthantai]

I have 6 monitor (4 monitor with vga connector and 2 monitor with dvi connector)
I need single or dual gpu can use in one pc to display all monitor with cheap price
My country sell even hd5xxx and gt210
Any idea ?

Btw : my pc hace 4 pcie x16

Using 6 monitors that don't have native displayport is going to be very expensive, this doesn't seem like a very good idea to me. The graphics cards you mentioned are not powerful enough. You will need to get at least an hd 7870 and a card with a displayport 1.2 connection. Then you will need a 1x to 4x displayport hub, and then you will need 4 active displayport to VGA adapters for the VGA monitors and you can hook up the other two however you want to the HDMI and DVI ports on the card. This isn't going to be as cheap as you're thinking.

I see hd7770 vga with 2 dvi connecter and one hdmi
Can i use 2 hd7770 with 2 dvi to vga and 1 hdmi to dvi ?

Well you need displayport to run 3 monitors off of a single card according to AMD, so technically no. Everything I've read on using two cards to power separate displays says not to citing driver issues, but it might be possible to run 4 monitors adequately using this method. This thread might help you.

There are a couple of ways of doing this, though as others have mentioned, the biggest issue is the VGA monitors.

As @chemmajorp53 says, the "proper" way to do it is with an MST hub on an AMD card. Here's a four way DP++ hub, which would allow you to use 4 DP to VGA adapters: http://www.club-3d.com/index.php/products/reader.en/product/multi-stream-transport-mst-hub.1655.html
But you're talking several hundred US dollars for the adapter and cables.

I've had very good success in the past running multiple graphics cards on Win7 and later. Assuming you're talking about just desktop use, and not gaming (which is a totally, totally different story), you should be able to use multiple cheaper cards, or a card and your integrated GPU, and it'll all work pretty seamlessly.

Do you have integrated graphics? How many display outputs (and of what type) can you get from that?
Do you have a graphics card already? How many display outputs (and of what type) can you get from that?
Can you post your motherboard and CPU so we can see what's possible?

Are those 4 VGA monitors really VGA only? They don't even have DVI inputs? That would help!

Yes i think that problem is vga monitor, but the MST hub is not cheap anyway

Yes I'm not playing game, just for office work

- My PC don't have integrated graphics
- I am using Dell T3610 with C602 chipset
- Yes it is 4 VGA monitor only, It was very easy if it have any digital connector like DVI, HDMI, or DP

I think I can buy another mainboard + cpu that have 3 integrated graphics and 1 VGA ?

You've got an E5 CPU and server grade motherboard, upgrading that won't be cheap, especially if all you're trying to do is get integrated graphics.

You've got loads of PCIe slots, are they all filled? If not, at least try and pick up a few cheap graphics cards and run them together. I know @chemmajorp53 was raising concerns about using multiple graphics cards, but honestly, I've never heard of major issues. Running SLI + a PhysX card isn't particularly unusual, and works fine. That's three GPUs in a system.

Given that you can pick up a few GT 210 or GT 610 GPUs for peanuts (compared to any other solution we've proposed so far), it's absolutely at least work trying. An MST hub + adapters is going to hit $400+ easy by the time you get everything you need, and a new CPU+Mobo will run north of $600.

@chemmajorp53, if you have solid reasons or evidence for the concerns with multiple GPUs can you post back here? I'll admit it's not something I've done a lot, but have in a couple of builds productivity (not gaming) builds and have never had any issues whatsoever. But that's of course only anecdotal.

Yes I have save think

new CPU+Mobo will run north of $600.

What type of cpu + mobo ?
It TOO expensive in my country )

I think you misunderstand. I'm encouraging you to pick up some dirt cheap GPUs run them all together.

GT210s have a VGA and a (most, I believe) include a DVI-I too. That will allow you to run 2 VGA connections using a dirt cheap DVI adapter. Those cards start around $35 US. So should be available in your region for cheap. I'm suggesting you pick up two or three of those cards, if you have the PCIe slots.

Some earlier posters have suggested you might have driver issues. I have done this a few times in the past without any problems whatsoever. I'm not guaranteeing it'll work without any problems. But it's so cheap compared to other options that it's at least worth trying.

Thank you, Now I have finish with an Asrock H71 mainboard and HD5870
The mainboard support run IGP even when VGA is running, so I have 2 more output (DVI + VGA)
The HD5870 have 2 DVI, 2 mini DP, 1 HDMI, it easy to have a passive adapter 2 DVI to 2 VGA , and I still have 3 digital output, I just need buy 1 active adapter from HDMI to VGA

My combo take
Mainboard : 20$
CPU (G2030) :40$
HD5870 : 50$

Total only 110$ and some cost for adapter
