SLI question

[lolitsjack]

So a long time ago I used to run two cards in SLI, I don't even remember what they were. As I understand its somewhat combining the power of the cards to really increase performance. However I am going to be doing a new build that needs 6 video outputs for screen. Right now I am running 3 screens off of a single GTX 970 that has 4 video outputs. Lets say I got another of the same card to add another 3 video outputs (Running multiple video game clients, one for each output). Should SLI even be considered at this point? Can it even be done? Would it hamper the affects with them competing for resources from each other? Does SLI disable the second cards outputs and uses processing power to be used by the first?

Unless you're using Nvidia Surround, SLI will disable the outputs of the 2nd GPU.

You cannot use more than 4 displays on consumer nvidia cards regardless of how many GPU outputs you have.

That's a per card limitation isn't it? And it's hardware limited I think.

SLI won't benifit you in your use case. It's more for a single application. Since you have many games clients it would make more sense to allocate each game client to a GPU so they are properly shared.

The limit is how many outputs there are, or 4 displays max. Whichever comes first. You'll need a second card for additional displays.

If latency isn't a factor you can try something from Plugable

Thanks for replies! Going to get two cards when they come out, probably 2050s or 60s

Highly unlikely anything under an 80 class will support SLI or NVLink.
