I would say 2 x HD 7970s for 3 x 1080p.
3 x HD 6970 will work with 3 x 1080p but seeing how 2 x 6970 could bary handle BF3 i dont thing the 3rd card will run tides.

I think your watercooled HD6970 Tri-fire is very comfortable with 3x1080p overall speaking.

For 3x27'' (3x 2560x1440), use the table below for estimation:- (note the driver used was not too recent)
213

1) For the six columns (4 through 9) involving HD6970s, only column 8 is Tri-Fire while the others are 2-card CF. Unfortunately, the Tri-Fire 6970 setup gives little info as it crashed so often (likely due to using Portrait Mode which is not much supported by earlier drivers).

2) I suggest you to use Landscape Mode (vs Portrait Mode) as it is more 'stable'. Therefore, use column 6 (in red rectangle) for main reference. Going from CF to Tri-Fire, the theoretical max is 1.5. So, say, apply a 35% (30% for GPU scaling and 5% to account for 2560x1600 vs 2560x1440) gain in those ave framerates and then see if the fps are acceptable you.

(source:-http://www.overclock.net/t/903852/3x-30-portrait-6970-cf-eyefinity-vs-580-sli-surround-showdown)

Also, member Levesque is running 3x2560x1600 and I think he has some experience with HD6970s at this resolution as well. PM him for advice.

Is that Vegas thread? He had problems setting up quad 6970s and blamed it on AMD when it was user error. Regardless though, it's still not fast enough, any number of 6970s/580s on massive screen sizes. You'd have to be clocked to the nines to get there and that's just not realistic for 98% of people.

1 7970 plays very well in most games on 3 1080p screens. You may be able to sell the trio and get a 7970 for no extra.

You need two 7970s to get 120fps avg in BF3 with med settings. To do ultra, like read ultra you need three especially with three 1440p panels.

If I may suggest, stick to the panels listed here AMD Eyefinity Compatible Display Panels

 

 

Why? To ensure all games supported in Eyefinity comply with Windows for the reason below.

 

All display devices (monitors, projectors, and televisions), analog or digital, must supply Extended Display Identification Data (EDID), which is stored in the monitor’s EEPROM. Sometimes during manufacturing, incorrect or incomplete EDID might be flashed on the EEPROM. Such EDIDs can lead to problems such as setting incorrect display modes. This white paper describes how monitor manufacturers can avoid reflashing the monitor’s EEPROM by implementing a monitor INF that overrides part of, or the entire, EDID information in software.

Isn't a 7970 weaker than 6970 crossfire? Would be giving away performance by selling three 6970's, although i'm not sure how three 6970's would fare with two 7970's seeing as the third 6970 isn't meant to scale so well.

A word of warning, eyefinity can be a massive pain in the arse, not only because alot of games won't support it at launch (and never will, hence you have to for hacks from the community) but it also highlights the utter incompetance on AMD's part when it comes to crossfire support, on a single screen you may not notice it too much if you have high end cards anyway so one card will be enough, but on multi-screens you need every bit of power you can get, and this is where it fails alot of times giving sub-par performance in the end.

I think I made my choice with all of your advices. I think I'll go with a 1440p for now, then later buy 2 mores if I decide to upgrade with two 7990 or two GTX 680 (4GB only).
