Nice job and some good info here on your benchmark results...

Thanks appreciate it! I hope it is helpful.

Updated with 3dMark Results. Not too shabby for air cooled video cards.
 

4way is best，except 780ti
I'd suggest titan to set up a 4way-SLI , especially on 4k or surround
though you have very high scores , but in game we do need stability and more v-rams , the score in 3dmark is nothing , soon you'll forget it
I think 2way 780ti on 1080p or 3way 780ti in 1440p is smarter , 4way 780ti in multi-displays is probably a wrong way
hope you test some games with high visual effect settings
 
msaa will bring a much clear picture , not like the dim screen from smaa/txaa , so please use 2msaa (or noaa if acceptable) , and tell us the v-ram loss
that's why in 4way-SLI we must use the double v-ram (150% BF4 texture-mappings are brilliant , but video rams drop too fast)
 
and when on 8msaa (and other hi-pressure options such as god rays and hbao+) , the cards will have to be in stressful conditions , the ROPs  max-out and you will see the real side of both graphics and cards : glorious picture , stable card . or failed .
you should buy a next-gen new flagship for the surrounding screens . 780ti is not matching the resolution you're using , it's fast but not balance.

Great work man,thank you very much for the info..
They really kick!!!

A lot of the games above are using 4xMSAA, 8xMSAA (with 8xTRSSAA), and/or SSAA. I understand why vRAM limits would be an issue at 4k but lets also look at the fact that if someone wants to game on one 1080p or 1600p display for more than 2 years, 3-way or 4-way may not be a bad investment. At that point, a few generations of video cards have passed and then you can "feel" that upgrade with another 3-way or 4-way system al over again. I wouldn't say 4-way is a "wrong way", just depends on what you are looking for out of your system.
 
BF4 does stutter a good bit at 5760x1600 with 4xMSAA due to vRAM. 2xMSAA is more acceptable in performance. I initially wasn't going to multi-monitor this system but I decided to for testing purposes.
 
Now that Dell has announced some cheaper UHD monitors, it may be time to rethink aspects of the build.
 
Titans may be an idea, but they are hard to come by these days it seems.

good job! i was thinking going quad. but after reading your thread, i think i'm going stick with 2/3 gtx 780 ti. quad is blowing money away. you don't gain much performance from adding the 4th one  thanks! and good job bud!

If you go 4k with Crysis 3 or BF4, the 4-way seems to scale well. Basically the games that didn't scale well were CPU bound games, or games that utilized PhysX.
