Are you using (or planning to use) Crossfire or SLI?

Please elaborate (or comment) in the thread if you would like to.

No, because it would exceed my power budget. One high-end card is about 250W, so two would be 500W, which is more than any fanless PSU can supply.

 

[Yakk]

Been running sli & CF setups for the last decade+. In the last few years mostly CF from extra mining cards I have anyways.

 

[railven]

Need another option "No, I've used SLI/CFX and have zero interest in the headache."

AMD's CFX Pacing issue broke me. So I tried NV's "superior SLI" only to find it wasn't any more superior.

One card to rule them all.

 

[WhoBeDaPlaya]

Switched from a pair of R9 390s to a pair of 1080s, albeit temporarily (second 1080 is headed into another rig RealSoonNow)

If I can pick up another 980Ti for $120 within the next 2 - 3 years, I will probobly run SLI then. Otherwise, ill be buying somthing along the lines of a 1080Ti (or equivalent) for no more than $200 within 2 - 3 years and run that for a while, rinse, repeat. My last card was an HD7970 that I bought used about a year after release for $120, I came from a quadfire HD6970 setup before that.

I am done with multi card setups until something magic happens to fix all the problems. Ran crossfire with 5850's, 6870's, 7950's and 290's and SLI with 780's and 970's. Performance is too dependent on drivers, often only mediocre scaling, tons of heat. Now I would rather spend the extra and just get a more powerful single card and not deal with the shenanigans.

Ive ran single, dual, tri, and quad setups before. Every time I ran 2 cards, performance was always better than a single in every game/application, and there were no unpredictable drawbacks (obviously power draw was greater, and depending on the board I used, the top card ran hotter). Once you start using 3+ GPU's, its usually not much better than 2, and frequently worse, especially with 4 cards.

I used to run SLI GTX 660s a few years ago. It was a terrible experience. When they worked, it was great, but half of the time something would be wrong. Lots of games didn't have support ever, others only got support when Nvidia got around to putting out a driver update, and some had jitter problems. I would have been much better off buying a GTX 680 (I couldn't afford it at the time). The only way I'd recommend SLI to someone (for gaming at least) is if they are buying two of the best single-cards. That way, if SLI works, you get amazing performance, and if it doesn't, you still get very good performance.

I've been running dual gpu from the 4870X2 to 7950 crossfire. Since then , modern game engines have become increasingly unfriendly, hostile even towards multi gpu so I am holding the same stance.

The good thing however is that modern lower high end cards can handle 1080p just fine, so I'm ok.

 

[guskline]

I've had in SLI 660s and in CF 290s and RX480s. I just sold one of my 480s in hope of Big Vega to appear. I'm done with SLI/CF.
I'd rather opt for a single fast gpu.

 

[biostud]

Using a 7990 so cf.

 

[Elfear]

Like many here I've used various multi-GPU setups from both companies over the years. Compatibility with different games, while never awesome, seems to have declined over the past couple years to the point where I don't believe it's worth it anymore. Most frustrating experience was trying to get Bethesda games to work with Crossfire.

 

[SlowSpyder]

Trice CF once. It was ok. No plans to go back unless there is some new wow-feature that comes out with using multicard. I imagine most systems with multiple cards in them today are mining.

 

[IEC]

Not interested in multi-card setups for gaming at the moment, though I have multiple multi-card rigs for other purposes (including mining).

 

[Grubbernaught]

I've previously run Sli for the last few cards (580, 680 4gb, 970, 980ti) but currently run a single 1080ti. Considering a second for surround (3x Asus swift) but just not sure the compatibility is high enough on recent releases to warrant the outlay.

I can say that going from 2x980ti to a single 1080to has been worthwhile and feeds a single 1440p 144hz well enough to not bother with Sli for single screen gaming.

 

[Reinvented]

Minimal gains going to SLI or Crossfire, for increased power usage and heat dump in a case. Not worth it. A single GPU that's strong is good enough for my games.

 

[vbored]

The last couple of years multi gpu has gone to hell. If you can get support normally the scaling is pretty average (fallout 4, witcher 3 comes to mind), the battlefield games were generally the golden child for support and scaling but it was starting to get broken regularly in battlefront then again in battlefield 1 after patches. I think the money for a second gpu is probably better spent on a variable refresh monitor at this point if you already have the fastest single card around.

 

[Termie]

To add some cold hard facts to the discussion, I thought I'd offer up my recent GTX 1080 Ti SLI benchmarks at 4K.

I've been publishing SLI benchmarks since the 980 Ti SLI generation, and scaling is definitely getting worse, but it's a whole lot higher than zero.

For comparison, here are the 980 Ti SLI benchmarks, obviously with an older set of games. Game support is the biggest issue, not the drivers. Crysis 3, for example, now scales far better than it did with Maxwell, but the BF series is a lot worse.

Another factor in all of this is CPU power. GPUs have increased dramatically in power over the past 5 years, while CPUs have only increased around 40%. My 6900K@4.3 is now a bottleneck running 1080 Ti SLI at 4K in a wide range of games.

 

[EXCellR8]

abandoned 24/7 multi-gpu long ago; today I only run a pair of GTX 980 in a spare computer for SLI optimized games.

Game support for SLI/CF is basically just making each frame render as independently as possible. Performance changes between architectures are most likely down to drivers, or changes in the hardware, which are, again, the driver's job to handle.

 

[darkswordsman17]

Need more options. For me, I would consider it if they make it compelling. There's been talk about having a GPU render each eye for VR that could be interesting.

 

[DaveSimmons]

I want my games to "just work" even if that means running at a lower resolution or with lower settings.

So I buy the best single card at the time (last 2: 980ti, 680) and run the card, CPU and RAM at stock speed. No worries from being only 99% stable, no headaches from weak multi-GPU support. Also lower noise and power usage.

 

[Micrornd]

I use 2 x MSI 7970 Lightnings in Crossfire to run either 5 monitors in Portrait mode or 3 monitors in Landscape mode, depending on whether I'm playing or working 😉
Both are in real x16 slots and I can't say that I've had any problems with them.

 

[aigomorla]

I used to be on SLI 980Ti x2 ... however i am done with it. I am now on a snigle 1080Ti for my main.

Ive always used SLI... since voodoo2 days, however i am sick and tired of nvidia and SLI drivers not working.

I am tired of them being broken all the time. and having issues like now where my monitors dont sleep on windows 10.

Rarely do you get launch day support for SLI, which means you only have 1 card rendering until Nvidia decides to release SLI drivers.

So from now on i decided to have a single "Titan / Ti" class, instead of SLI "GTX".

But my 2 cents with SLI... don't unless u absolutely need it for something like 4K on multi monitors.
