To each their own, but my scenario is playing games that are a bit older, sli is supported usually, and I crank up all the settings and include AA, I dont want to turn down quality. So in this scenario, SLI is very feasible, as it allows me to max any title on my monitor which is 4K, and I also dont care for 120 fps, all i need is fast vsync @ 60 hz.

no, 60hz, and 40 fps is not considered good, when SLI gives you double that or at the very least 50% more.
Nothing like 2x price, 2x heat, 2x power, and 0-70% performance increases.

price- enthusiasts pay for the best, money is no object,
heat- nothing to write home about, the gpus normalize themselves and the clocks according to power and temps, no special heat up in the case.
power- only when gaming, otherwise it is zero essentially. and two 180w gpus are not that much.
performance- you try to get what is possible and available. Also as I said with RTX you need every bit of gpu power.

It is the opinion of those who do it whether or not crossfire or SLI makes sense. I will say it comes down to specifics. I used crossfire mostly for Total War. The thing is I see such an improvement in the games I play like AOTS (100-110 consistent FPS @ 4K), Strange Brigade (165 FPS @ 4K), Kingdoms of Amulur (265 FPS @ 4K) (Yes I do play this game), Shadow of War (85 FPS @ 4K) and TWWH (45-90 FPS @ 4K). I have Vega cards so it is not that bad gaming with a single card and the other card is completely turned off when that happens. The heat thing is also not something I feel as my cards are water cooled. I do get how the dislike camp feels because it never really took off on the developer front, there are only about 500+ games that support crossfire and obviously Microsoft promoted multi GPU support in Windows 10 to assist adoption rate as there was really no reason to get 10 otherwise. I am sure many people from both camps were more than interested in that promise.

WOT is the best (after Tolkien) fantasy series I have read the characters on both sides were so strong. I also like how polarizing the multi GPU debate can be. It's either love or hate apparently.

I miss dual GPU. In this era of slowing tech advancements, multi-GPU is the easiest way to get more power, given GPU generations are taking longer and making smaller steps every time. "crossfire" in the old sense may be dead, but Crossfire, as in some multi GPU solution, isnt going to stay dormant forever. MCM GPU configurations will be the future of high rez high hz gaming setups once we cant shrink nodes anymore.

The subject has come up in this thread that multiple GPUs in Crossfire or SLI are necessary for 4K which isn't correct . I just checked the review of the 2080 Ti FE here and of the 23 games benched at 4K only 3 fell below 60 FPS average.

Deus Ex: Mankind Divided 51 FPS
Ghost Recon Wildlands 48 FPS
Monster Hunter World 43 FPS

Most of the rest were way, way over 60 FPS average.

Bear in mind also that these games were benched at their highest quality settings. For the very small handful of games that don't perform to your expectations then you could turn down the settings a bit. I'm not defending the price of the 2080 Ti but you could go that route with 4K. It is possible.

I expect the 3080 Ti will probably be quite a bit faster than the 2080 Ti.

But 4K gaming is still a niche market even after all of these years. It's for people that are willing to pay for it.

The major problem with dual card implementations is games have to be aware of it and a profile configuration for game is required on crossfire and sly.

Neither company is focusing on it as it's difficult to get max performance out of both cards and to split the workload between 2 cards.

So those griping about it, 10 of the world's smallest violin players are playing the song, "my heart bleeds for you"

I gave up on SLI when three AAA titles i tried to play with official SLI support either had lower performance, or visual issues (killing floor 2, certain items wouldnt render on second GPU and would flicker really goddamn fast)

when nothing worked except benchmarks, SLI and Xfire became redundant

Exactly my point and I know you ain't the only one with those problems. So Lisa Su is making the right decision for her company as a whole.

To each their own... but it irks the heck out of me that its 2x everything except performance (which can vary dramatically from no improvement to around 50-70% depending on many factors). I don't want to have to look for profiles and play reindeer games. I just want to play games.

I'd rather not deal with any of those hassles and buy an appropriate single card for the money. Any of the games where a 2080 Ti doesn't reach 60 FPS can easily be adjusted to do so considering the settings TPU runs at (Ultra - which typically includes AA).

Can't say I will complain about SLI and Crossfire going out. Its a waste of time, because really, what we would do with all that dev time is get maybe a 10-15% discount on a certain performance level through the second GPU (better perf/dollar lower down the stack) in exchange for endless fiddling and tiny nuisances like microstutter, heat, reduced OCs, it just being broken, etc.

I always kinda wondered if multi GPU didn't just exist for the epeen value, and then 'oh yeah it also adds some performance'. It does feel good having a rig full of hardware, never mind the practicalities.

Dual GPU has been dead since 290x. Devs don't care. They can't even release a game without a day one 15GB patch. It's all a joke just like gaming in general, today. AAA titles are crap, microtransactions (along with pay2win), sold on lies, etc.

Remember when gaming was good? Pepperidge Farm remembers.

You must be fun at lan parties :rolleyes:

Gaming's in a pretty good place if you care to look beyond the frontpage news, really. Maybe its just burned out in general for you?

I miss dual GPU. In this era of slowing tech advancements, multi-GPU is the easiest way to get more power, given GPU generations are taking longer and making smaller steps every time. "crossfire" in the old sense may be dead, but Crossfire, as in some multi GPU solution, isnt going to stay dormant forever. MCM GPU configurations will be the future of high rez high hz gaming setups once we cant shrink nodes anymore.

You're actually very right about that. But we also place higher demands on our games now, the dependancy on VRAM I think was a catalyst for SLI's demise. Nvidia started killing it right at the same time AMD started looking at HBM; and Nvidia had to move to delta compression, and VRAM capacities doubled overnight.

Now look at today; high end GPU between Maxwell and Pascal gained another 4GB (970 > 1070) and the high end even goes to eleven ;)

This makes it even harder to sell 'wasted' hardware resources like doubled VRAM. And I reckon its also harder to push all that across the bridge/bus. Nvidia had to scale those up already.

I think inevitably you will meet the same problems with SLI/Crossfire as you do with MCM solutions, but with MCM you can solve it all within a single chip/design/board, and with much shorter paths.

The subject has come up in this thread that multiple GPUs in Crossfire or SLI are necessary for 4K which isn't correct . I just checked the review of the 2080 Ti FE here and of the 23 games benched at 4K only 3 fell below 60 FPS average.

Teehee. I remember the 1080ti reviews and I saw those exact same framerates across the testing at 4K. 60 FPS 4K (as in minimums) is fár away from us. And yet, price is soaring for marginal performance bumps. Look how long it took for us to say we can finally 'kill 1080p' with a specific GPU. And even then some new games cripple even the higher end models at that res.

Games evolve. A resolution bump is simply a major bump in your requirements for smooth gameplay, and it won't ever be fixed by new releases if you keep playing new games. Well, it will, but you can safely look at periods of a decade for that to materialize. I think many people can now say they made a major mistake buying into 4K gaming (monitor, mostly) as GPU performance increases slow down.

I ran SLI for 4k gaming so 'worst case' of one GPU not working was a total bust, when one GPU couldnt handle it... and that worst case was often the case with official SLI profiles where nvidia gave up

Please do checkout this video of mine, quake 2 rtx, impossible to play or render unless two such cards work in SLI, as RTX features require every bit of gpu power. However, I'm glad that having bought the cards in 2016, I'm still able to enjoy features that get upgraded with time.


these are the cards

and the result of RTX port royal benchmark, again, depending on SLI

One more thing, I'm sure the high bandwidth SLI bridge does it's share of the workload, especially at exteme resolutions.

I had CF 6850s and never again. Many times I played with a single card because profiles weren't out for a bit.

I think you'll find that you could use a regular bridge and not lose much if anything.

You cant rtx on non rtx cards....right?

The HB bridge is good depending on the titles at 4k+ resolutions. Some testing saw no improvement to a peak of 25% in one title (others were single digit to 10% or so when it went negligible).

I think you'll find that you could use a regular bridge and not lose much if anything.

Yeah but I sprung for the cards, only to skimp out on the bridge? I did read that it does help with flow of data in 4k and high settings.

You cant rtx on non rtx cards....right?

The HB bridge is good depending on the titles at 4k+ resolutions. Some testing saw no improvement to a peak of 25% in one title (others were single digit to 10% or so when it went negligible).
Of course you can, nvidia brought pascal support for RTX, haven't you read about it? (of course with the shaders, not with dedicated cores for rtx)

Benchmark Scores Faster than yours... I'd bet on it. :)
Oh my... yes I recall now! But it's still applying a function, even with dedicated hardware on rtx cards, that neuters performance.

Yes you can, performance is just about 80% lower though.

@Vayra86 :
Do pay attention that your vram clock is a bit high, and there is a performance hole somewhere in that region, as opposed to say +300 mhz. Is your card COMPLETELY stable on these clocks? And you may get a used one to add and do SLI...

Hehe yeah if I put these clocks in an SLI setup they probably won't last, I'm right up at a temperature limit really, but running 100% power target. I actually lost perf on this card when increasing power target. I bet this would make a fine OC'er under water...

But as it is, my 1080 has been running as in my specs since I bought it and hasn't crashed once.

Gotta say its an interesting thought, that Q2 of yours looks reasonably playable too. Although I do get the impression from the video you suffered some mad input lag. Bumping into walls, couldn't time your jumps, slow mouselook... Or were you just enjoying the scenery?

Nice share anyway, watched the whole thing ;)

Ok, I decided to upload the MUCH BETTER QUALITY (than youtube) video to mega, so people may be able to enjoy the quality in full.

It almost has an eerie quality to it, seeing that realtime reflection on the gun in the otherwise blocky environment. And yet not 'out of place', more like some kind of uncanny valley sense I get from it.

Nice, though you do really have to look for those little details. I have to say the overall lighting quality still looks rather dull. I mean, a point light source doesn't do that much other than it used to with old tech, and because of the low poly count, there isn't much 'happening' as you move past them.
