I've read that this XFX BE 7970 can support 6 monitors, but it only has 4 outputs. How is this possible? Is there an adapter you can buy to split the outputs?

Here's the card: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Apprently, from what I've been able to discover, if you wish to run 6 monitors with the HD 7970 you will need an add-on component in the form of a displayport 1.2 hub. These haven't hit the market yet, so 4 monitors is the most it can support until they do. You can read more about it in this review of the gpu >> http://www.pcworld.com/article/249030/amd_radeon_hd_797...
I guess this is going to be a bit like the whole displayport debacle where all these monitor manufacturers claimed they'd support dp, but models are still rather thin on the ground.

Edit: More on the displayport 1.2 hub here >> http://blogs.amd.com/play/2012/04/26/displayport-1-2-%E...

Well 6 monitors are usually supported on the cards that state Eyefinity 6 but there are Display port adapters that allow you to use 3 monitors from one display port but they are $150 or more at least the ones I could find.

You've found a hub? Can you post a link please.

Thanks unksol. Now if I can just find somewhere in my country that carries them, I can finally get a couple of people off my back, although I don't think they're going to be too happy with the price. (This is what they get for ignoring me, lol)

Each DisplayPort connector can be daisy chained to drive two displays

Couldn't i just use this instead?

And since this card doesn't have display ports, only MINI display ports, it seems pretty obvious to choose the hdmi hub lol.

Is there a reason why the hdmi hub is so much cheaper? It seems to have WAY better ratings than what the other adapters.

Edit: A little more scrolling brought me to this 5-in-one adapter. Would putting almost ALL your monitors on one connection give you poor performance?

That's an HDMI splitter, not a hub. It's just used to redirect one video source to multiple destinations. HDMI and DVI cannot be daisy chained, they can only carry one video signal. DisplayPort can carry multiple video signals but the individual resolutions are limited by the link bandwidth. A DisplayPort splitter requires significantly more hardware than a simple HDMI/DVI splitter which is why they're more expensive.
