Just picked up my last three GTX 780 Ti SC video cards. I must say I'm pretty impressed with the performance so far. It's about what I expected. There are some anomalies with the testing. I did do this is somewhat in a hurry (for example, only did each test once, and didn't include any surround gaming). I'll update this as I do more testing.
 
I need to do surround testing with this. One monitor (except for 4k) isn't enough to really push this setup that hard.
 
None of these were canned benchmarks (unless an actual benchmark program is added).
 
***NOTE*** I had to reinstall my 331.82 drivers when I went to do the 2-way SLI tests for 5760x1080 only. I didn't realize but on all of the other tests I had texture filtering set to "High Quality". So most of these benchmarks show the "worst case scenario".
 
*** Update ***
Got a pretty nice 3dMark score on this hardware!
 

 
Batman Arkham Origins
Some weird results in testing. I want to run more tests for consistency sake


 
Battlefield 4:
Good scaling here. Again I'm getting close to a CPU limit I believe


 
Bioshock Infinite:
Scaling here worked well up until the 4th card. I'm most likely seeing a CPU limit or something other than the GPU at this point.


 
Crysis 3:
Things start to improve scaling wise here. Not too shabby.

Adding in my 5760x1080 benchmarks. Will post them as I have them complete.

For single monitor 1440p / 1600p SLi 780Ti is the sweet spot...equivalent to my previous Tri SLi 680 Classy's.....anything more than 2 of these cards is just throwing $$$ away unless you're planning multi monitors...

I used to run three 30" monitors but I only have one left now (didn't use them all that much.) I'm going to work on some 5760x1080 benchmarks and see how these numbers shift. I imagine they will a good bit.

I do know on the games that are GPU bound that they still scale at 4 cards. This is great news for when future demanding games show up.

good info here

Lots of great info here and great work on the graphs

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

Thanks appreciate it! I hope it is helpful.

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.

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!

can you please share what tool you use to get fps number for bf4.  thanks.

can you please share what tool you use to get fps number for bf4.  thanks.

You can use Afterburner as it has x64 support. Funny thing is, I installed Afterburner to see the fps in Titanfall, but then the free period ended. Went back to using Precision.... Now it shows me fps in my 64bit games... This is on a G19s keyboard LCD, didn't try the overlay.

thanks for the benchmarks...I'm planning to upgrade my monitor to the new Asus Rog Swift when it comes out in Sept and thinking about adding another 780 ti to my sli setup already. this helps a lot.

Hello clayton,
thanks for sharing your tests results. I'm thinking about buying a third 780 ti classified into tri SLi for my surround TVs but
I am little afraid that I have weak power supply for three cards with OCed CPU and GPUs.

Nicely done clayton! Thanks for the info.
