Can 6970 CF support eyefinity 3 x [2560 x 1600]?

Can 6970 CF support eyefinity for three LCD with res: 3 x [2560 x 1600]?

Also what are there any games that can support such high resolution? Is it a waste of money?

Yes and no. I had some issues running games at 5790 x 1080 (3x 1080P monitors) with my lone 6990 (which is slightly lower in performance). I had to lower some of the ingame settings in things like BFBC2 (No AA), Crysis 2 (had to settle on High settings instead of Ultra with DX 11/HiRes pack), and Metro 2033 (couldn't run AA, had to lower a few settings).

Also, games like COD and some older games don't support it and you have to do manual fixes or just play on one screen. It was a waste of money to me as after a few months of playing with it, I eventually switched to one larger screen.

Kind of. I had 2 6970's on mine. Some games ran fine, others weren't playable at that res.

And yes, heaps of games support the resolution.

Thanks for the input. I think the whole eyefinity thing still needs time to evolve...

The tech is good, the issue is that there's just not enough horsepower. One 6970 will have a hard enough time pushing 1600P let alone three times that res. You're going to want to start with 3 cards.

3 1600p screens will require quadfire to run modern games at decent settings.

Yeah, it's fun when it works. It was just too much of a hassle for me to run games from. Also, randomly when fullscreen some flash videos would stretch strangely.

there was a previous OCNer here that tried quadfire 6970's with your res and it did NOT work. I would go with 2 6990s, IF you have the money. But that resolution is so awesome that playing at lower settings would be ok because it is a complete eyegasm, it truly is awesome to have one of these 2560x1600 monitors.

The user who was unable to get it working made the erroneous conclusion that the crossfire bridge didn't have the necessary bandwidth to accomodate the 12 megapixels. He was and is incontrovertibly wrong, though never redacted his complaint. I've seen triple crossfire & above flawlessly push 11 & 12 megapixels with full AF & 2xEQAA. Quadfire allows maximum in game graphic settings in every or near every current title; of those, 16xAF was also operable & in 75%, so was 2-4x EQAA. Considering the incredible horsepower & GPU syncronicity required for those phenomenal rendering settings? Truly an accomplishment.

I have eyefinity and a good idea is to set up 2 diff profiles with your drivers.
One is the eyefinity screen 6048x1080 (in my case)
the 2nd is 3x 1080p screens.
You switch between with a simple ctrl+alt+1 or ctrl+alt+2

The 3 separate screens allow you to expand a movie, browser, single screen program/game with no overlap to the next screen and perform the same as a single screen setup.

Switch to the eyefinity for your wide screen games with a ctrl+alt+2 adn off you go.
