Is SLI / Crossfire not relevant for the moment?

You are correct.
This is how it's been for years now, SLI/CF has been dead outside of raw compute tasks for a long time now
Tons of continuity problems, consistency/timing issues, and lack of support.
Next time look it up first.

There will be a point where the pci bus wont handle the throughput and the need for multiple GPU's will be common place.

>>58954710
PCIe 2.0 x16 is more than enough for really any GPU on the market, there's not a lot of PCIe throughput really, and it's not likely to shoot up anytime soon
But if you are concerned, PCIe 3.0 is twice as fast as 2.0, and the upcoming PCIe 4.0 is twice as fast as that, and PCI/PCIe scales perfectly with the new standards
so I wouldn't worry

So then I've been wasting my money on buying 2x 1070s and 2x970s and 2x670s?

Goddamnit....

Oh well at least I know now. No wonder I don't notice any difference

Also, shouldn't nVidia and AMD be doing something about this?

Surely it hits their profit when people have very little incentive to buy an extra card?

>>58954749
That is all true though
GPUs don't rely on the having more than 16GBytes/s bandwidth to process basic rendering input data and export frames
I mean it's not the bus that's processing your graphics

>>58954763
It looks cool and ignorant people assume 2 must be twice as good as one when in reality it's only 30% better if you're lucky, and only in 10% of programs if you're also lucky

>>58954749
What's wrong about that post?
You ever seen tests of PCIe bandwidth affecting gpus? It makes your prediction look fucking retarded
You could handle 3 high end modern gpus off of PCIe 3.0 x16, shit AMDs been releasing single-slot crossfire cards for years

You're cute when you explain the things to people that already know.

>>58954805
What you're not getting is that GPU performance isn't based on input bandwidth you're being a shit who clearly doesn't understand the understanding of clear data and shit, you look at page and stop and never come think that when you why do you think you have know anything here??

>>58954685

The scaling just sucks way too much for the cost.

The only good use of multiple cards for near linear scaling is computation and rendering, which aren't even actually SLI/CF, just individual cards.

You have redeemed yourself young shitposter. You may continue in your thread unabaited.

I don't think dual gpu setups were actually ever relevant when it came to playing games. In the past decade I can only think of a handful of games that were optimized to work with dual gpus. Outside of benchmarkings, they are a waste of money. And game devs clearly have no intention of dedicating more resources to make sli/xf work in their games when the people who run dual gpu setups are a very small minority.
