Should I buy GTX 1080 or stick to 980 Ti SLI?

    Currently I have Zotac 980 Ti AMP Extreme in SLI, so should I consider to buy GTX 1080 over my current setup? I saw GTX 1080 3dmark firestrike benchmark and its just above 2k score from my single 980 Ti which is not impressive to me? Please help me to decide.

    Are you talking about replacing both cards with a single card, or are you talking about replacing 980 Ti SLI with 1080 SLI? If you're only planning to grab one 1080 then it's going to be a downgrade in anything you do that uses SLI.

    According to Hardwarecanuchs, one perfectly OCd 1080 (2150MHz) can almost outperform 980Ti SLI (vanilla stock). The benefit will obviously be that in those games that SLI scales poorly (FarCry Primal for example) the single 1080 should perform way better.

    Single GPU is almost always better than SLI due to price, heat and noise and singel GPU performance. SLI is better when scaling is perfect (like SW Battlefront) and you have AIO (in the 980Tis case).

    It's obviously up to you to take the decision but it wouldn't be a terrible idea if are lucky enough to get a golden sample and are running your 980Tis in stock clocks. That's if you are tired of bad SLI support and noise/temps.

    Wait for 1080ti if you must have something different.

    That's the obvious answer. Question is if OP wants to wait another year or not.

    The Witcher 3 is also an excellent game that scales fantastic with sli :)
    Both cards almost 100% gpu useage while running true the woods :)

    Performance is almost double with sli with that game.

    If i where u wait first for a third party custom gtx 1080 from msi or gigabyte then if its really faster then a gtx 980 ti in sli, then u could also sli them if u have the cash.

    gpu useage is 95 to 99 % on 1920x1080.

    if you dont go for 1080 SLI then upgrading is a waste of money.

    I was thinking something similar as to yourself as regarding my setup , i would like to go back to a single card setup , but the 1080 from what ive seen so far would just be on the edge , as my monitor has a native resolution of 2560x1440p and i must have full eye candy and settings n game , i think that the 980ti sli has the lead in fps and games that support sli .

    I veiw going to a single 1080 as not a upgrade to anyone with 980ti sli, and only a 1080 sli would be, wait for better cards to come along , especially if your monitor resolution is higher than the standard 1920x1080 .

    Not the same scene. If anything, the second scene is heavier. Let's assume they're equally demanding.

    Framerate: 102.1FPS / 62.2FPS = 1.6415 --> 64.15% scaling.
    GPU usage: (97% + 97%) / 99% = 1.9596 --> 95.96%.

    There you go.

    On CrossFire, it's different though. They are proportional.

    I can do same scene gimme a sec.

    After i am done with eating i make same place shot with sli on and off its still huge u will see.

    This is with max settings everything ultra, hairworks on everything.

    I never go single gpu unless the GTX 1080 Ti can beat my GTX 980 Ti in SLI or coming very close to it.

    I dont even own a 144 hertz panel yet [120 hertz @ 1080p atm] if i upgrade to say like a 1440p monitor @ 144 hertz i need more power then this, a single gtx 1080 just wont do it personal for me with frame rates under 60 fps @ 1440p.

    SLI off

    My cards are about the same as the 980Ti SLI, and I honestly see no reason to upgrade until "big" Pascal GP 100 is released. A 1080 Ti or Titan type card is the true upgrade, in my opinion. At any rate, that's what I'm doing. I'll upgrade, and SLI the GTX 1080 Ti when it's released. I'm in Canada, so I'll have to wait for a few months before it gets anywhere near here.

    here are my benchmarks and I'm very satisfied, so decided not to go for GTX 1080 and I don't think that single GTX 1080 even OC can beat 980 Ti SLI at least not mine AMP Extreme edition :). What you say guys???

    Here's the thing. The GTX 1080s you saw being reviewed yesterday, are just reference models. Aftermarket models are almost always going to be much better than reference models.

    In about a month, you'll see GTX 1080s with custom cooling and two 8 pin connectors which will probably have factor boost clocks as high as 2.4ghz or more, and the VRAM overclocked to over 11ghz.

    At that speed, the GTX 1080 will be about 40% or more faster than a GTX 980 Ti @ 1500/8ghz, with much better DX12 performance.

    I have the same card as you, and I'm wondering if it would be better for me to sell it and just get an aftermarket model to tide me over until the GTX 1080 Ti comes out next year.

    If I don't sell it soon, the value of my card will plummet. Next year it will be worth about $300, vs the $550 or more I can get for it if I sell it before the GTX 1070 comes out.

    When the 1070 comes out, Maxwell GPUs value will drop like a stone..

    As per their benchmark in BFHL single 980 Ti is about 32fps and with mine in SLI scaling is over 100% that means i'm having over 100fps @ 4k with everying thing maxed out with 4x MSAA just WOW, and GTX 1080 performs 42fps @ 4k, if you'd even OC GTX 1080 it'll max reach 50-52fps, so i don't see upgrading to 1080 over my 980 TIs.

    Sorry, but you can't get over 100% scaling in SLI :grin:

    I used SLI for 7 years before I switched back to single GPU, and I'll never go SLI again.

    SLI has it's uses, but how much of your cards' power is being wasted due to its inefficiency?

    And with the low level APIs, the majority of the responsibility for supporting multi GPU is now with the developers, yet most of them couldn't be bothered to implement it in their games and or engines due to the massive QA factor.

    And if it is implemented, the scaling is terrible.

    Like I said, not worth it. Dropping SLI was one of the best decisions I ever made when it comes to computers.

    But Carfax you can see my benchmark results BFHL and 3DMark I'm getting over 100fps as i uploaded my picture just look at that... I guess scaling is good with Maxwell

    I cant see your pictures for some reason but I'm also one guy that didnt manage to get 2x performance out of Witcher 3. Single GPU OCd I had about 75fps and in SLI (stock) I got max 100fps.

    Probably CPU/memory limitation.

    I get 90% scaling on it.
