Hardware & Technical Black Friday SLI question

Since it is Black Friday soon I was toying with the idea of looking for a deal on a second 1070 to go SLI.

I have never used SLI before so a couple of questions:

Does Elite Dangerous still have issues with SLI?

Do I need to have EXACTLY the same card as my existing one (Asus Strix GTX1070 8GB DDR5 OC).


For info - I run 2560 x 1440 27 inch monitor, I won't be going VR (done it, sold it) - my PC is i7 6700K 4.2 Ghz 16GB DDR4 Ram on an Asus ROG Maximus VIII Hero - I don't overclock.

Finally another question, would I really expect to see any difference for my outlay? I say this 'cos the game runs like silk with no stutter or FPS drops as it is although I might up my monitor to a larger one, say 4k at some point.

Never seen anyone say you don't need exactly the same cards.

You need the same GPU/major model, preferably with the same memory capacity, but identical part numbers are not a requirement (and don't always imply identical properties anyway).

I've done it once, never had any issues at all with any games or overheating.

This looks like a comprehensive set of tests - https://www.guru3d.com/articles-pages/geforce-gtx-1070-2-way-sli-review,1.html They are testing at 5K res in one test and getting 66 FPS vs 34 FPS SLI vs single card - that's a nice jump. 4K is 100 FPS vs 56 FPS for SLI vs single.

SLI profiles are developed on a per-game basis, and trying to use a profile for a different game or a custom profile can be quite hit or miss.

I've had a few SLI setups, though none in the last few years, and while I could get most games working without problems, this was far from universal.

HeavyGrooves and jon flint here have both had major issues with SLI in Elite: Dangerous on their RTX 2080 Ti, which while new, should be seeing the most support.

I did personally get positive scaling last time I tested, but that was in 2015 and the game or drivers could easily have broken SLI support since then.
 
Many games work really well with SLI, I've run through a few and uploaded vids to YouTube, Elite isn't one of them sadly:

The vid was done with sli 1080ti's, I was only mad enough to buy a single 2080ti!

I was at one point getting some positive scaling with elite, not sure if was a driver or a game update that broke it, but right now, it tends toward negative scaling :(

+Morbad beat me to it :)

Oh that really is a shame it doesn't work with Elite. I've seen quite a few people posting about their SLI setups, didn't realise there were such serious problems.

That video - I can see why you were mad!
 
Thanks everyone, that confirmed my understanding that E D was problematic. So I'll save the dosh for now and wait to see how the 20series progresses.

Thanks again. [up]
 
Is SLI still worth buying? I mean, Nvidia cut off SLI from 1060 models where it could be potentially good.
What's for high end gaming cards it is useless, I think. Even a single 1070 has enough performance to run 1440p at 60 fps.
GTX 1080 and 1080ti are more than enough even for 1440p at 120 Hz.
RTX 2xxx series is a good choice for 4K resolution. Don't mention ray tracing enabled. It is another question.

I think if you've got something like a 1080ti, going sli can help bridge the gap and get you to 4k/60, since a single 1080ti isn't really enough for 4k in most titles. If you game at 1440p, adding a 2nd card can also help push to 144hz if that's your thing.
