Since there are now a lot of new cards from Nvidia and AMD that do have output designs optimized for multi-screen users, this thread is getting a bit outdated. However, if you own either of these cards, you can still come here and get support.

NOTICE: This thread also covers the Asus HD7970-DC2T-3GD5, since they are essentially the same.

Estimated date of release in the UK: 22nd of Februari. This is probably the same for all of Europe, although I haven't found any exact dates.

There seems to be a problem on the 'T' cards with voltage regulation to the GDDR5 memory that can only be hardware fixed. Sweclockers.com has had direct conversation with Asus people, no source link yet. This has been fixed.

FYI: This thread covers the new Asus 7970's and the MSI R7970's, which are at this moment out on the market. Here (thanks to sparx) you can find a cool article on the making of the Asus cards. Additional info will be put here when we hear it. Furthermore, I will make an in-depth review about the card when I recieve it.

Original thread below.

Okay, so I recently stumbled upon this 7970;
http://www.asus.com/Graphics_Cards/AMD_Series/HD7970DC23GD5/#specifications


This card features four Displayports and 2 DVI connections (one of them is dual-link, but requires an extra clock. This will disable one of the Displayports via a switch on the card.
[hr]
MSI also brought fourth there version of the 7970, which is slightly better in performance;
http://www.msi.com/product/vga/R7970-Lightning.html


This card features the same amount of outputs, but MSI opted for Mini-Displayports instead of Displayports. It does not have a dual-link DVI port.


Post/ask anything about these cards here, there are always people here to help.

I hope to see this Eyefinity and mixed output tearing myself one day. I have 2x DVI and 1x passive DVI to DP (XFX branded, like EUR12 on Ebay).

This would indeed eliminate tearing, so the card might be a good option for you. The cost of three active adapters seems high though. As long as there isn't tearing on my center monitor I don't notice it, but you do?

Well, I've looked up the adapters again, and the price is only around 20 euro's. And since I've already got one, that means I'd only have to spent 70 euro's in total over a reference AMD 7970 to eliminate a tearing issue. Now that, ladies and gentlemen, is interesting. Also, the card is overclocked and has a great cooler. I think I'm going for this one.

PS: ik ben ook Nederlands :p

The ASUS DCII and Sapphire Flex E6 are the only cards I'd bother with if you want the maximum options.

I might ben considering this card too, but it has no hdmi port for my tv :(.

Would it be possible to connect the tv to the hdmi port on my motherboard (Intel integretad graphics)?

Well, intergrated graphics are disabled the moment a PCI slot is in use by a GPU. You could connect your tv via the included HDMI-DVI adapter, but I'm guessing you want a direct HDMI for the audio.

You'd have to find someone else to tell you if you can enable your intergrated graphics while having a GPU in the PCI slot.

AFAIK Z68 boards have this Lucid Logic Chip built in, which enables usage of IGP+GPU.
