Dual. Quad is for benchmarking or people with extremely deep pockets. It serves no purpose in the real world because many games struggle to use 3x GPU's, a 4th is pointless, infact, alot of the time quad SLI performs worse than two way.

+1 for the guy above me .infact you dont even need dual SLI unless you have a slightly older card or want better performance...

Quad SLI is "iffy". Veryt few sites regularly publish benchies for it. But here's 1

http://uk.hardware.info/reviews/2725/8/nvidia-geforce-g...

Picking 3 popular games, ya can see that 3 and 4 way SLI can be useful, problematic and waste of investment

GTX 680
Game - 1 card / 2 cards / 3 cards / 4 cards

AvP - 59 / 107 / 158 / 205 @ 1920 x 1080 hi settings 4AA
AvP - 27 / 49 / 64 / 89 @ 5760 x 1080 hi settings 4AA

BF3 - 67 / 120 / 128 / 131 @ 1920 x 1080 ultra settings 4AA
BF3 - 25 / 98 / ?? / 57 @ 5760 x 1080 ultra settings 4AA

Skyrim - 120 / 206 / 219 / 223 @ 1920 x 1080 ultra settings 4AA
Skyrim - 51 / 96 / 97 / 130 @ 5760 x 1080 ultra settings 4AA

AvP showed a pretty consistent increase and an argument could easily be made that it has a ROI at 5760 x 1080, especially if using 120 Hz
BF3 showed passing 2 cards as detrimental and dint work 3 cards
Skyrim showed no reason for a 3rd card but a half hearted reason for a 4th

Keep in mind that these tests are generally done as soon as a card drops into the channel and subsequent driver releases generally remove the anomAlies by building new SLI profiles.

Would running surround at 1080p with dual sli be okay?

yes it would just fine just make sure you use powerful cards.

1. As to the need .... that will vary by individual and how many monitors they run. If that need includes Metro even at 1920 x 1080 and Batman AC (in 3D)

At 1920 x 1080 .... Metro 2033 manages just 30 fps w/ a single 670, 50 fps in SLI.
At 5760 x 1080 .... Metro 2033 manages to break 30 fps only with w/ 3 way Crossfire
At 5760 x 1080 .... Batman AC manages to break 40 fps only with the 670 / 680 in SLI both of which do 49 in 2 way. Turn on the 3D and that fps drops significantly

2. Whop doesn't want better performance :)  ?

3. Also cost .....

Two 560 Ti's cost 80% of what a 580 cost but had 40% better performance
Two 650 Ti Boosts costs just 80 % of a 7970 Ghz Edition and yet outperform the 680 and 7970 Ghz Edition .
