3-Way SLI on X99?

[Peyton Ouano]

I'm currently in the market to build an X99 PC. So far my build is planned to be:
Intel i7-5820k
MSI X99S SLI Plus
Corsair Obsidian 750D
EVGA 850w bronze psu

My question is, will there be any incompatibility issues if I use three GTX 780s in SLI? I've heard about three-way SLI issues with X99 motherboards or i7-5820k, but I'm not very educated on the matter.

MSI specs show that all three will run at x8 pci with the i7 5820.
The 780ti can pull 300 watts(each) when stressed with Furmark.
You will have a terrible minimum to maximum ratio frame rate with 3 way SLI(frame stutter).
