x8 3.0 per card would be enough

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

SLI requires 8 lanes, so 16 is enough.

It is, but Nvidia only allows SLI in 8x.

Me too, but that's what Nvidia hard-wired it's GPUs to do. If they don't have 8 lanes or more, SLI don't work. However, back when PCIe 2.0 is the norm, SLI happily starts with each card at 8x, but remember than PCIe 2.0 x8 has the same bandwidth as PCIe 3.0 x4, so.........
