    I already own a 1080TI. I get solid performance at 4K, but could be better as sometimes in games the system drops down to 30-45fps. So I'm looking to upgrade.

    I can't decide if I should go SLI route (thus getting better performance in some games, but possible multi-gpu issues), or go the single card route. I've had 4-way multi-card at one point and I remember the problems I'd get occasionally; makes me want to steer clear.

    Anyone have 1080TI SLI want to chime in on their experience?

    Go always with the single GPU route as always as possible without hesitation, in multi-GPU you will vastly outperform the 2080Ti but multi GPU only works in couple of games and synthetic benchmarks you will have an idle GPU most of the time .. a 2080Ti should be anywhere from 35% to 50% faster (even more in certain selected tittles) than the 1080Ti at 4K and I thing that may be the typical case scenario you may hit with going SLI 1080Ti but without any SLI issue and a much more smooth experience.

    I cant believe people even consider SLI especially when there is a single card option. Do you want to have a card just sits there in more than 1/3 of AAA games and the vast majority of Indie games? Do you want to deal with some poor scaling even in most games that do support it? Do you want to deal with worse frametimes and some micro stutter even though you may have better FPS? Do you want to deal with waiting for support when a game launches and perhaps having a game update or driver break SLI? Do you want to deal with chasing down fixes and having workarounds for games that can have flickering or other artifacts with SLI enabled? If all of that sounds fun to you then knock yourself out. Personally you could not pay me to use SLI.


    "The debate whether SLI is on the decline has pretty much been settled a while ago, probably when the promises of DirectX 12 mixed multi-GPU never got fulfilled"

    "you might be surprised that only about half the titles in our test suite actually scale with SLI. Out of 23 titles, 11 titles showed negative or no performance scaling when switching to SLI"

    Pretty easy choice man. Just did the move myself. There is no reason to go 1080ti SLI unless your primary concern are the few games that work well in SLI.

    Otherwise, games like AC Odyssey, etc all simply do not work with SLI.

    Yeah pretty much, the era of SLI is over. And it's like they want it to die.

    I wish it wasn't like that, as I already make use of multiple cards for rendering and video editing, it would be good if I could use them for gaming as well.

    What games, cause alot of newer games are supporting sli.

    I'm on the fence at either selling my sons evga 1080ti ftw3 hybrid or adding it to my rig.. I know the new tomb raider will love it at 1440 res as its needed. Also the new cod black ops 4 uses sli but at the same time it runs so fast it's not really needed. The new Battlefield will again use sli.

    Also will you have more then 1 slot spacing? Top card will get pretty hot in sli. Water cooling is what you'll want or the top card with a hybrid cooler.

    Basicly months ago I used my sons unused 1080ti with mine for 4k as that's where you'll want SLI for. Once I bought a 34" 1440 120hz ultra wide screen I didnt need sli..

    But now with newer games that need is creeping up for 1440.

    BO4 doesn’t support SLI that I know of. The new Battlefield should though. I got SLI working in the BFV beta using nvidia inspector and had great performance (although it introduce menu screen bugs). I’m sure for the final release BFV will run great in SLI.

    Someone answered me in another thread to me asking about SLI and he said the beta version did SLI in cod bo4.

    It didn’t for me. I googled if a workaround exists and I couldn’t find one. All the professional reviews I’ve seen indicate it doesn’t work. I’m genuinely interested if a workaround exists though, even if I’m not running SLI anymore. Have you found one?

    Even if a game *supports* SLI does not mean the frame times will be good. The experience can be worse even though your FPS looks higher.

    What drove me away from SLI besides the obvious is even if a game works now does not mean it will work the next game patch or driver release. Nothing is more enjoyable than trying to squeeze in a quick game to find your FPS is way below a single card.

    The 1080ti sli vs 2080ti is even more of an assinine comparison since it sounds 60Hz is targeted in this case where you’ll see ~35-55% increase from a 2080ti PLUS eventual RTX features like DLSS. The baseline is basically SLI all the time (factoring in frame times) plus you might get new tech to fiddle with later.

    Considering every benchmark I've seen shows it not working with CoD WW2 - I doubt it works with BO4.

    Although it is possible it -could- work with the latest CoD's if you turn off all postprocessing features - But at that point it's just stupid.

    As someone who runs SLI, I would recommend getting the 2080 Ti and not dealing with dual cards.

    There is an edit feature for a reason as there's no need to post back to back to back in a matter of a few minutes for every random thought you have. And maybe you didn't bother to look at the link that I posted? SLI support is going down not up so not sure how you get that confused. Last year when techpowerup did their review it was nearly one-third of the AAA games with zero support and now it's basically half the AAA games with zero support. And again as I've mentioned over and over even in the games that do support it you're going to have issues most of the time. You people have to live in a fantasy land to think that SLI is worth it at this point except in a handful of games.

    I'm actually fine with double posts, because it shows the notification that a new post was made. If you just edit, people might not see the update.

    There's no point in making 3 posts in a row in 5 minutes though. In fact most forums will actually give you a warning for that and a ban if you continue to do stuff like that as that looks just like you're trying to get your post count up.

    Then please follow the rules and report me now. I've been here long enough to know better.

    Like cyber mentioned I did it cause I was afraid the OP would miss my edit.

    Editing for mom.. see if she sees my edit.

    You've been a member since March 18th 2014 and have 3440 messages and I've been a member since dec 7th 2003 and I have 2636 messages..

    So your point is that I spam alot with a alot of unnecessary mesaages??


    Yeah another though that I want to add with hopes that someone sees it.

    Ya know maybe you check and see if a mod possition is open on this forum since you like to point out such injustices in your presence. If your post was to limit my posts you went about it the wrong way cause I now have to respond to you making more posts.. should of just contacted a mod or pm'ed me your issues with my intolerant act.


    Wait.. one more edit.. hope you catch it!

    The point is if I go back and edit the post, it does not show a "new" next to the message.. so with a large thread it's real easy and common practice to scroll real fast past my edited message and totally miss it on the next visit to the thread.. so there ya go.. point proven cause every time (4th) time now I go back to edit my post you wont know!

    Someone might just miss that important info that would help there issue or decision making process.

    LOL so you're really going to use that excuse? How could you possibly think he would miss what you have to say when you posted 3 times within 5 minutes? Do you think the person starting this thread is blind and or a complete idiot?

    Is there anything even left to talk about as far as SLI goes? The person starting this thread has already been given a good factual answer. Other than that there will only be a few replies from people that are completely out of touch and thank SLI works great.

    I'd say SLI overall is probably a headache, *but* if you need the power it's the only option.

    Well I guess you can run at a lower res or reduce settings, but if you want max everything, then SLI it is.

    There are only two main instances where it makes sense.

    1) You're buying the fastest card on the market already and it's not enough.

    2) You have a really old rig, and can get a second card for cheap used on ebay.

    Otherwise, just buy 1 of the fastest card you can afford.

    It's going to be game-dependent. So the OP could talk about which games they think need a boost, as a second 1080Ti could be quite a bit cheaper for a boost if they're looking to purchase soon.

    Or he could skip out on all the SLI related bullshit and just get a boost in every single game he has by getting a faster single card especially since he's playing at 4K...

    Read what? The person starting this thread has not even made another comment. In what world do you live in that selling a 1080ti and buying the 2080ti cost 4 times as much as getting another 1080ti? I'm no math professor but it seems like about the same damn cost to me in the end.

    Sell 1080ti at $600 at best. Buy 2080ti at $1250-1350. Sounds like a win :/ .. or buy a used 1080ti for $600 if the games you play support SLI. 1080ti sli faster then 2080ti.

    1080ti to 2080ti isint that big of a jump for that kind of price.

    That is some pretty fucked-up math that you have. There is a model from EVGA that is a thousand bucks but let's just say 1200 is the cheapest he can get a 2080ti. So if a 1080ti is worth 600 bucks according to you then that means it will only cost him $600 after he sells it to get the 2080 TI. If he buys another 1080ti that will also cost him $600. Can you really not do basic math? That is the same fucking price. What kind of idiot would go out and fool with SLI which doesn't even work in half of the AAA games not to mention all the headaches in the games that it does work in when he could just get a single card for around the same price that will give him a performance boost in every single game?

    I don't understand your point.. your point is only valid if a 2080ti is just as fast as 1080ti sli.

    Spend $600 for a little faster or spend $600 for alot more if going sli.

    If sli is needed for the 4k title with all maxed setting and a single card is not enough cause maybe someone blew $1800-2k on a 120-140hz 4k screen then I guess the best option is go sli and much cheaper at another $600 then $2400-$2700 for 2080 sli.. or just sell the monitor and buy a cheap 60hz 4k screen.. or just play at 60-70fps on a 150hz screen.


    Oh and btw.. did ya see my above edits on the prior page? Oh thats right cause it's easy to miss those edited posts!

    Excuse me while I go and install that other evga 1080ti ftw3 for sli and buy tomb raider game to max out the settings and enjoy 120fps on my 34' 1440 120hz gsync screen.

    I hear that game is really ruff on a single 2080ti at 1440. Butal at 4k.

    Edit:

    About 5 months ago I stole my 9 year olds (8 year old at the time) 1080ti ftw3 to pair with mine just for tomb raider in 4k. Of course I put it back after I was done with the game.

    So once again I'm gona steal his card again for the newest tomb raider.. he dont care.. he's busy playing fortnight eith his ps4 friends.

    OR
    You could STFU already and quit posting like you have to have the last fucking word! Look at your last 3 posts, just can't let it go can you?? Everyone, stop posting he is the end all of this THREAD!!! Watch this....

    IMO...stands for In My Opinion, which is what I think (we all know by your posts above what you think, WE FUCKING GOT IT Captain Last Word!)

    And back on topic, if the games you play support it and you get it at a cheaper price, than by all means SLI. I have never had a problem with it from my 660Ti's to my 970's and probably will get another 1080Ti Black Edition to do it again, because it is still cheaper over all and IS SUPPORTED in games I play now, except AC:O which I haven't touched in over a week. Like I said it depends on YOUR variables and what you need want. If it gets me my 4K performance and cheaper, it works for me then.

    Good luck and enjoy!

    Do you really have trouble with basic reading comprehension? If it's around the same price and it gets performance gains in every single game then it makes more overall sense. I guess in your magical world the person starting this thread only plays a couple of games and they just happen to be games that work perfect with SLI? Is that really the reason you're coming up with? The person starting this thread is playing games at 4K so he will get an immediate benefit in every single fucking game he plays at that resolution if he goes with a 2080 TI. If he goes 1080 Ti SLI he will only get an improvement worth a damn in some games out there as we've already proven that only about 50% of games even work with SLI at all. And again that doesn't cover all the damn issues even when the game does work with SLI. Of course I'm just talking to a wall because based on your comments here even the simplest concepts do not sink in.

    Anyway I'm done with this thread so if you want to keep making silly comments go right ahead as common sense really does not prevail here for you. I think the person starting this thread can now figure it out on his own just how stupid SLI would be considering it's the same damn cost as going with a single faster card that will be a benefit all the way around.

    I have SLI 1080 Ti's as well as CFX Vega FEs. No intention of giving either setup up for a 2080 Ti. I would go dual 2080 Ti anyways if that to me was worth it (it is not). Playing Shadow Of The Tomb Raider in HDR, consistent 100FPS, Max settings using DSR (rendering at near 4K downsampled to 1440p) is the best visual experience in gaming I've ever had and smooth as butter. In this case a 2080 Ti would not match that.

    So yes there will be games that would not benefit or would be hindered with SLI or DX 12 mGPU but the ones that play nice a single card will not touch either. It is simple when a game does not play nice, disable SLI or in my case use CFX which worked perfect for FarCry 5 at 4K FreeSync and later FreeSync 2 with HDR. Just because you have two cards does not mean some games will suck, a single card can be used if needed and games that usually do not support SLI or mGPU usually don't need it anyways but a single card will not perform like two when two are really engaged.

    Now would I recommend buying two 1080 Ti for $1200 over a 2080 Ti - probably not but buying a used good 1080 Ti to pair up with another owned 1080 Ti - you bet.

    I've been doing Sli since Sli has been a thing.. started with 2 3dfx voodoo2 8mb cards and quickly swapped to 2 12mb cards. Been with it again since nvidia has been doing it. Even had a quad 7970 amd crossfire setup then quad 480 to quad 580s. Dual sli since.

    Everytime I read about people posting issues with SLI I cant understand why.. never experienced any of that shit. In fact didint even know about nvidia inspector with sli tweaks till prob a year ago haha.

    Maybe some folks just can't stand the thought that some games play very good on a single card and their second card is not needed - like Doom. It is also extremely nice having those extra two barrels when you can use them to accelerate way beyond just the first two Quadrajet barrels. Just like the Serious Sam Series VR games, the Vega FE's just blows away the 1080 Ti's since CFX VR works perfect with all of those games in VR. Have no idea what the point is if not all games work with SLI that then it is = Bad or some crap like that. Unreasonable expectations but thinking a 2080 Ti will outperform two SLi/mGPU 1080 Ti's when both are pumping out frames is also missing the mark.

    In short the 2080 Ti in games that don't support SLI/mGPU will outperform the 1080 Ti around 30% for current games and same settings. For games that support SLI/mGPU the two 1080 Ti's will kill the 2080 Ti especially on the ones that scale over 50%. As for stuttering etc. games that support SLI/CFX/mGPU don't have that issue in my experience. Also rendering artifacts I've seen periodically more so with SLI/CFX/mGPU but normally for me insignificant, if so then I go with a single GPU if the game is worth it.

    Yikes, this has gone in so many different directions. Fun little read...haha.

    Here's what I'm thinking - I'm going to wait. I wanted to pull the trigger so bad but I should wait for a few factors. Been overclocking the 1080TI card and in most games I play (BF1, BLOPS 4, Overwatch, Star Wars BF 2), it gets between 40-70+ FPS maxed out in-game settings. These are playable at 4K, although I would like for it to be a bit smoother. However, if I wait a couple months, 1080TIs will go further down in price (will probably go the used route), and stock will hopefully balance and replenish for the 2080TIs (right now, they are a bit inflated - and mining isn't even a thing now). It just makes sense to wait, despite there being a better option out there.

    Thanks for the feedback from everyone.
