    Lots of games still support SLI, but there are many where there are small performance gains and some where there is a loss.

    It's definitely not guaranteed, but some big games do work like Far Cry 5 and Shadow of the Tomb Raider (this has developer mGPU support so the scaling is amazing).

    If you're interested, do some research and make sure that games you want to play will work.

    After running SLI for many years, I would consider micro-stutter to be dead. Nvidia (and AMD too) had introduced improved frame-pacing a few years ago, along with the bridge bandwidth improvements, it's gotten much better.

    In my case, I'm running 144Hz G-Sync monitors, which makes it basically a non-issue. Granted, if you look at the graphs they are still more spiky than a single card, but on high refresh adaptive sync you won't see it practically.

    It can depend on the screen size but, in general, AA is still needed, even at 4K.

    For example, if you have a power line wire or fence, or something only occupying a thin stripe of pixels, it can still look bad.

    People also forget about motion, where small movements will make an edge shimmer or snap pixels, which is greatly mitigated with AA, though post-process AA can take care of this without a high cost.

    Yeah, I'm that way with screen-space reflection. After seeing all the nice reflections, I can't go back to the always janky cube-maps which look so fake.

    Sorry if I'm spamming this thread, but I wanted to give an update on my rig.

    Not only is 4K here, but above 4K high refresh Nvidia Surround is also now here.

    I'm running triple 1440p (7680x1440, about 33% more pixels than 4K) at 144Hz and I'm able to drive it up to around 90 fps on High settings in new games.

    This is amazing performance. I've had these monitors for like 4 years now and it's always been a struggle to run at that res.

    Granted, still not on Ultra settings, but High looks great to me still, and 90 fps is more than enough for a smooth experience (G-Sync is key, though).

    Oh yeah I forgot about gsync and freesync monitors that make jitter less perceivable

    but isn't SLI on the way out? Some new games doing even support SLI and they say they never will.

    Multi-GPU/SLI isn't widely supported these days but not really on its way out either. Far Cry 5, Strange Brigade and Shadow of the Tomb Raider came out with mGPU support this year. Not sure about BF 5, BF 1 had SLI support. Personally having two cards has other advantages like more display outputs.

    Plus, one card just looks lonely in the case.

    LOL, that is the perfect argument when you have to persuade the wife that you need to spend even more money on your rig!

    “But honey, can’t you see how lonely it looks? So sad setting there all by itself? Surely you can understand why being two together is better than being alone. Right? Right?!”

    :D

    I'm also running a similar surround setup - 1440P / G-Sync

    Did you run 1080Ti SLI before the dual 2080Tis? I'm curious about the difference in performance.

    I'm on a single 1080Ti and thinking about adding a 2nd since they're around $500ish second hand.

    Maybe next year I can upgrade, but hoping to hang on for a couple years for a bigger performance boost from the next gen cards.

    That machine was running regular GTX 1080 SLI. The performance jump to RTX 2080 Ti was noticeable. I'd say in the 50% boost range.

    I didn't do any in-depth comparisons, but games that were just making the cut before are now totally smooth (Dying Light was one in particular I stopped playing because it wouldn't perform well an now it's at 100fps).

    A second 1080 Ti would be nice considering the cost. However, selling your Ti and getting a single 2080 Ti would be better in non-SLI supported games and also side-step SLI bugs.

    As I like dual cards, I would support getting the second Ti, but definitely do some research if you haven't SLI'd before so you know what to expect (namely that things don't always work).

    I appreciate the insight.

    I've run 1080P Surround and SLI on the GTX 480, 680 and 780 and now a single 1080Ti on 1440P

    I've always had a good experience with both features. There are plenty of games that run great on my system in surround but any demanding AAA title needs to be run in single screen mode.

    A single card would be preferable both for compatibility but also for heat (which is a major issue in my small 10x10 office)

    I've even thought about downgrading back to 1080P monitors (but this time with G-Sync)

    If the 2080Tis fall close to the $1k mark in the spring, I would consider picking up a pair.

    However, as much as I like Surround, I think it's too wide - the outer half of the side monitors doesn't add enough to justify the pixel burden.

    For me, the idea screen would be one of the new 5120x1440 panels in 120/144Hz with G-Sync - but the gaming gods have decreed that all new exotic panel configurations will be Freesync.

    Much wider than a 21:9, easier to push than surround and no bezels.

    Sigh.

    Yeah, Surround does kind of waste the outer monitors, you can barely see them (but I think it still adds to the immersion, the fact that the screens fills your horizontal vision).

    Starting over, I'd probably got with a high-refresh ultra-wide. I think that would be the best compromise, good performance and no wasted pixels (plus, no bezel).

    However, I like triple screen for work purposes, so I'll probably keep these monitors for a while (I got them 4 years ago, and they are still solid).

    Pretty funny how in the year 2028 the RTX 7050ti will probably do 8k 120Hz for $180. LMAO.

    More like $180,000 the way Nvidia is going.

    At that price, i might finally try multi GPU
