Unless you are a Miner Then it is all only Work.

I'm running 3 Way SLI with 1080 Kingpin. As for newer games getting away from it, Far Cry 5 is not the case, runs like a charm and actually solves an issue with screen flickering when you activate 3 way SLI, I'm running it on 3 screen 2K each, at 60+ FPS, highly optimized game.
 
Battlefield 1, is a different thing. That would run better in two way SLI, or even with a single card. We are used to be disappointed by EA anyways.
 
Battlefield 4 runs perfect, but will use all available resources, as it seems to be very inefficient with newer cards.
 
SimCity 5, forget about SLI at all.
 
It's been kind of complicated to use 3 way SLI, but in some cases you don't even have to deal with profile inspector. Stability has gotten better with the latest drivers.
 

STILL running 3 GTX 980 KINGPIN on Z77FTW FOR 6 YEARS STRAIGHT never a problem using 3 way bridge that came with mobo  oc i7 3770k 4.9 GHz on liquid   , never buying a new videocard after buying EVGA 3090 TI AND 3060 TI ,,,

Finally got my pretty sketchy 1080 Ti 3-way SLI setup going.
 
Using an dld, outdated x79 Classified motherboard.  I had a Xeon 1680 v2 CPU, but, the motherboard wouldn't enable the second PCIe slot to run 3-way (I tried 2 1680 v2 CPU's).  So, I had to put in an old i7 3930K and run them using PCIe 2.0 (3.0 doesn't even work on this CPU ).  It was still fun playing around and benchmarking.  3 different 1080 Ti's- Kingpin, Black Edition and Silver.  I might eventually find a different color to add to the mix.
 
Ya, I didn't feel like removing the backplates to give the fans space.  So, I wedged Q-Tips and thermal paste spreaders to give them some room.  Put a Delta fan on top to give them more airflow- it's just a test bench.
 

 

Nice. 😎👍
