Single GPU with 4 outputs **Urgent

[The Bru]

Hi

I urgently need GPU with 4 outputs. I was going to use the new Macbook pro, however there were problems with budget when I was suppose to buy it.

A single GPU with 4 outs will probably be 2 GPUs in one, like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102809

I need the 4 outputs for 4 different projectors, all projecting different things.

The cheaper the better, as his card will basically only be used for 1 night.

Otherwise, what are the possibilities of combining on-board graphics with a dedicated GPU?

Thanks

2 cheapie GPU's possibly?

I dont have any experience with crossfire/SLi. Any good guides?
Will that setup be okay with a 500W PSU?

HD 6870 eyefinity, has 6 outputs. I have 2 of them lying on my desk ....

Yip..

I'm not sure what cards are cheaper, but have a look around..
Note you will need converters if your projectors don't use display ports.

What inputs do the four projectors take?

Why can't he just use this? http://www.rebeltech.co.za/index.php?main_page=product_info&cPath=20&products_id=5020

EDIT:

NomNom looks rights..
Reading here, look for the Eyefinity 4 Setup.

If you want to use four projectors, they all have to feature DVI ports to make this work. The card you'll need is this one:

KFA² GT210 MDT @ R821

The ports are dual-DVI on the card and are digital-only. IIRC the MDT version comes with some separate screen management software that allows you to have a separate desktop on each screen. Otherwise if you have different projectors that use VGA, the HD7770 NomNom posted will work, but will require adapters for the HDMI and Displayport outputs. Alternatively:

Sapphire HD6450 Flex 1GB DDR3 @ R665

You can run three of the projectors off that card requiring one adapter if the projs have DVI ports and if your motherboard supports it, you can enable the onboard graphics for one extra display output. Support is board-dependant, so only go with the cheaper Flex if you know you can use the onboard GPU as well.

Wesley, does that that KFA 210 come with adapters splitting the Dual-Link DVI into 2x DVI-D?

Secondly, can you run monitors on both dedicated and onboard graphics simultaneously with any chipset that has onboard graphics? I know my 1 colleague runs 4 monitors (2 off a GTS250 and the other 2 off his Sandy Bridge motherboard), and then I've got another colleague who is doing the same with an older motherboard chipset, but he is using Linux and it was rather complex getting both to work simultaneously.

It Should as the Installation guide does list it, as the Ports on the GPU doesn't actually support a normal DVI cable

I think so. I've only seen the card once in person and I remember some cables were bundled, but they aren't regular splitters AFAIK. Its closer to a workstation card than anything, similar to those ridiculously expensive Matrox ones that cost so much you could buy a half-decent 2nd hand car with that money.

Secondly, can you run monitors on both dedicated and onboard graphics simultaneously with any chipset that has onboard graphics? I know my 1 colleague runs 4 monitors (2 off a GTS250 and the other 2 off his Sandy Bridge motherboard), and then I've got another colleague who is doing the same with an older motherboard chipset, but he is using Linux and it was rather complex getting both to work simultaneously.

It works only on specific chipsets. Any Intel board with the GMA4500 GPU is technically capable of it, but it is BIOS-dependant. AMD has been offering this as a standard feature since the HD5000 GPUs started appearing integrated into their AM2+/AM3 boards, but there is a slight chance that the BIOS may not have the feature written into it. I can get it working on my rig but I'd need more RAM so that I can allocate it to the IGP. Newer graphics solutions are capable of this as well, but the feature may be omitted or written out for whatever reason.

Case in point: The HD2500 GPU on the Core i3 and i5 chips from Sandy Bridge can support up to three displays but its dependant on the motherboard's support for the feature. Intel-branded boards, for example, won't let you use more than one display on the board, while others based on the same reference design will support it. Again, AMD works far better in this regard and you can actually have three screens off an APU and another three off a discrete GPU with each array doing their own thing.

any nvidia 600 series card not sure about the lower end cards but something like a 660 will do.
