Hey
 
This has never happen before sooo... with the 2080ti price increase. We can now get 2x 1080ti and still have spare £ left or 1x 2080ti. To be honest, I think the 1080ti is a better investment. Its going to be a long while before the RTX on gpu is usable and I'm fairly sure we will need 40+ GIGARAYS before it actually is good enuf for us.

What ya all thinking?

    Been waiting for the additional power and ram to run 7680 x 1440 with maxed out settings.  For me 22 GB RAM is a need 11 GB and the older hardware not enough to get the job done at the frame rates I demand with the settings I demand.  (why I held off on the 1080tis reviews wern't cutting it)

    Some great sales on the 10 series Now so, it all depends or your intended use and timeline.
     
    Value is in the eye of the buyer.
     
    2080 will not be release till mid/late September (Sept 20 is the Official Nvidia release)

    Just remember Not all software / games support SLI

    RTX Project EVGA X99 FTWK-5930K,EVGA2080Ti EVGA-1200P2  Nibbler EVGA X99 3-GPU Water Loop 1600P2  AIO Folding  1080Ti FTW3 Hybrid, 1200P

    A single 2080 Ti will be better at 4K in titles that don't support SLI/mgpu. In games that support SLI/mgpu gwo 1080 Tis will be faster at 4K.
     
    And $1200 is $500 more than I am willing to spend on a Ti.
     
    That's why I threw caution to the wind and got a second 1080 Ti, even though I hate SLI (due to waning support). I won't support that increase in price. I'll buy a used one in a year or two for half the asking cost.

    Hey
     
    Well I suppose its all down to the performance increase. If 2080ti is only 25% faster than1080TI, then essentially they are asking 2.5x more money for 25% performance boost. I dont think the 2080ti's are worth it at the moment with the sparse benchmarks we get. 
     
    Even still, the RTX rendering from what I can see only runs at 1080p at the usable frame rate. So I really find it more and more difficult to justify the price increase. Nvidia really need to release the benchmarks, or else this 2080ti generation is not worth buying. Its like intels overpriced i9 cpus that no1 really want and now every1 loses their (shirt) after 32 core amds ones - at least around me where we use our computers for CGI work. For me 2080Ti sounds great, but if I look at software/cost/ then 1080ti feels a lot better despite losing the RTX performance.

    I'm on the same side of the fence as you on this one.  I wanted butter smooth 4k gameplay on games like Total War Warhammer II.  You're not going to get that with the 2080 ti.  I already have a 1080 ti and it seems to me the smart play is to just purchase a second one and get the performance I really wanted in the first place.  I feel like there was a misstep here not increasing overall power (to equate to such a huge price increase) and VRAM.  I might have considered it seriously with the ray tracing performance if they'd at least bumped the VRAM to 15GB (still wouldn't have justified that cost though).

    Yeah good luck with your SLI where silky smooth experience is ruined by microstutters.
     
    I have been using GTX 970 SLI in the past and it was horrible. IMO always prefer single powerful GPU instead of 2 weaker ones.

    I would wait and see what performance reports are from users on the 2080 Ti before deciding between the two.
    Me personally, never had a desire to SLI so I just get the best single card I can afford at the time.
    I like the KISS principle.

    SLI is dead, guys. It's supported in so few titles, that more often than not, you'll experience worst performance going SLI than single. It's ridiculous.
     
    I am hoping NVLink will be the saving grace, but we'll see.
     
    I made this mistake, in the past, of going SLI instead of upgrading.

    If you already have 1x 1080 Ti I would either 1) stick or 2) sell the 1080 Ti and upgrade to 2080 Ti.
     
    If you don't have already have 1x 1080 Ti I would bite the bullet and go for 1x 2080 Ti. (Of course, we don't have the new performance specs yet, but if you are asking about SLI then your value for money sweet spot is likely to be different to the average PC gamer. I should know... I am in the same shoes as you. But I am waiting more because I want Hydro Coppers or Kingpin edition 2080 Ti, so by that time the performance testing will be available to read).
     
    SLI does offer some scaling depending on the game (somewhere between -10% worst case and +50% FPS best case), but you are adding a lot of extra heat to your PC, it is expensive and despite the theoretical increase in average FPS you will notice micro stutters which can be flipping annoying. Much more annoying in fact than more stable but c.20% lower average frame rates. Plus if you are not gaming in 4k, 5k or 8k, then 1440p will be great anyways with either 1x 1080 Ti or especially great with a 2080 Ti.
     
    I had 980 Ti in SLI a while ago and sold one of the cards after a few months use / experience. It just was not worth it.

    1080ti SLI performance sucks, I had it running for awhile, ended up pulling the second card. Some games literally perform worse in SLI, many games barely get at 10-20% boost. There are certainly a few ideal games but... not many. So between the two options I'd go with a single 2080ti.

    Since Nvidia is going to a new multi GPU architecture, NVLink, I wholeheartedly agree with you that SLI is dead. We will have to see what it brings to the table before spending another $1500 on a water-cooled card.

    Where are you finding new GTX 1080 Ti cards for less then $600? A RTX 2080 Ti is $1,200 and you said you can get two GTX 1080 Ti cards with spare money left.

    Where does it say "new" in the paragraph that you quoted. It doesn't, that's where :-P
     
    I picked up a used Gigabyte 1080 Ti FE for $493 off of Ebay - it works great, and I put it under an AIO cooler with a G10 bracket just like my EVGA 1080 Ti FE and both overclock the same.

    Used GTX 1080 Ti vs New RTX 2080 Ti isn't a fair price comparison, that would make the price comparison invalid.
     
    The post didn't say he would be buying used GTX 1080 Ti cards either. :-P

    If I'm not mistaken, the basic difference of SLI and Nvlink is that Nvlink shares the memory between the cards and every card's power is combined like one card, but SLI requires supported software which will divide the workload between the cards.
    So as already mentioned by other members, SLI is dead (a long time now actually)

    That's not what NVlink will be like at all for consumer cards, and it's clarified in a video. Forget the dude's name from Nvidia. 
     
    NVlink is a faster version of SLI, with a very high bandwidth instead of just a high bandwidth.
     
    Memory sharing won't happen because the link is too slow and will cause issues. It COULD theoretically be implemented by game devs, but you know that they won't but in the extra effort if they can't even be bothered to implement DX12 mgpu. And it will cause slow down issues, just like when your CPU has to hit the page file when you run out of faster system memory.
     
    As to the combining of cards into one so that games see just one device? I'd love to see where you read/heard that being the case because that's a fancy bit of software.

    SLI still works the same old way according to Tom Peterson of NVIDIA in a podcast. NVLink just gives more bandwidth for swapping the frames. Tom said microstuttering will always be an issue with SLI, even with NVLink. That is on top of all of the lacking SLI profiles and poor scaling.
     
    I was one a mega-SLI guy but now a solo GPU guy.

    No no no I didn't mean that 2 cards connected through Nvlink are recognized as one card, but based on this: https:// en . wikichip.org/wiki/nvidia/nvlink and the following image,
     
    The GPUs work as one under the CPU's orders. I may have understood the technology wrong but what I understood is that shared memory = shared workload. So a single frame can be worked by both cards at the same time.

    This may be the case for enterprise, science and education applications of this technology where MUCH higher bandwidth NVlink is available - it isn't in the game space yet.

    Also depends on what you are upgrading from.  If you are upgrading 1080TI to 2080TI...that is fine.  Memory bandwith is 484 to 616 GB/s.  Upgrading to a 2080 from a 1080TI is more questionable...since 2080 only does 448 GB/s memory speed

    Those numbers you're quoting are about Memory Bandwidth, not speed. And that number is a multiple of memory chips on the card. A 1080 Ti has 11 44GB/s chips. While a 2080 has 8 56GB/s chips. However, memory speed is higher on a 2080, on account of the new memory. 1080 Ti memory operates at 11Gbps, while 2080 memory operates at 14Gbps with higher bandwidth memory chips, even though there are less of them.
     
    Edit:

    Also, memory bandwidth isn't a big deal. The GTX 780 had 288.4GB/s memory bandwidth, but the 980 was 224GB/s. That didn't stop the 980 from being faster.

    Hello folks,

    What is the status nowadays?

    I’m running 2x EVGA GTX 1080Ti FE, not in SLI, I do play quite a bit but the main use of the computer is 3D. I stopped using SLI because I could not see any performance increase, it actually decreases when rendering for example with Redshift 3D. I'm planning to upgrade my PC and looking to spend as less as possible 😊

    Right now the base config is:
    Intel Core i7-5930K
    MSI X99A Sli Plus USB 3.1
    64 GB DDR4-2400 Crucial Ballistix Sport

    And I’m ready to order:
    Intel Core i9-9900k
    Aorus Z390 PRO WIFI
    64 GB DDR4-3000 Corsair Vengeance

    So, my question is, should I sell the 2x 1080Ti and get 1x RTX 2080Ti?
    I’m not sure it will be worth in terms of performance for 3D and Video rendering
     
    Thanks in advance for your help!

    Not to be that guy, but being that Zen 2 is right around the corner, I figure it might be worth it to see the results before pulling the trigger on a new system.

    Thanks, indeed mate, up to today 9900K, it's the CPU with the best performance for after effects which for me would be great as I'm doing a lot of 4K renders.
    Maybe I will look into that, but anyways, my main concern right now still related to the GPU as I don't have enough money for GPU and CPU/MOBO/memory upgrades :/

    I agree with your caution - would 1 2080 Ti be better is not an easy question to answer for that specific software

    I'd look at the 5960X or Xenon CPU for your current X99 MB if you want More power & upgrade that RAM to faster speeds 3200 as a minimum

    Why ?  Those new Z390 CPU Only have 16 PCIe lanes
     
    You would have to choose between having 1 - GPU & 1- M.2  - OR - having 2 - GPU


     
    Professional software - it is Always best to see what is recommended by the software company.  Many drives & other improvements are Only available in the professional GPUs

    If your determined to go Z390 .... get faster RAM than 3000 for increased performance
     
    If you just have to upgrade your Rig --> look @ X299 & some of those CPUs can support 44 PCIe lanes ... if your have the budget for them = Expensive CPUs

    Thank you very much!
     
    You right, I totally forget about that "detail" ha!
    With only 16 lanes, I would need to give up my M.2 drive, Wifi, and still running both GPU @ 8x :/
     
    Good idea, maybe I can get something like i7-6900K and some 3200 memory as you mentioned, what you think?
    In that case, do you think would be worth to change to the RTX?

    The 9900K(KF for me) is a marginal upgrade.  My new 9900KF at 5.2 is maginally better than 5960 w/OC'd fsb from CPU standpoint.  My gaming has been better with my 2080ti than my 1080ti fe SLI using hybrid kits.  But, I'm using the KP at 2160-2175, mem 8400.
     
    My sig below is not updated, but it's now 9900KF @5.2 Z390 Dark, 32GB Trident 3200C13, K|ngP|in 2080ti, with updated 970 pro and 970 evo M.2 drives.  I lost out on RAM with the Dark board and 16 PCI lanes.  Was a pretty easy OC, system runs cooler and gaming is better, but if you're rendering anything, I'd stick with HEDT.  I regret not getting minimally the 9900x w/x299.  Hoping for Intel die shrink on HEDT CPUs soon.  I'll wait for that.  As for the 2080ti, get something with the A die and higher power limits.  It'll be good until the next gen card is released, however the 1080ti lasted pretty long.
     
    At current prices of HEDT cpus, if you're spending $900 already, go 10 core or more.

    I can't put my finger on the information right now ..... There was something about Win 10 & Losing ability to OC that generation of CPUs
     
    edit: Found it  KB4100347: Intel microcode updates (messes with CPU

    i7 6900K Broadwell-E overclock gone in Windows ...
     
    Within budge at Stock BCLK - get the fastest RAM your MB will support. 

    Some X99 MB seem to have issue with some RAM chips changing the BCLK to 125 when it should be 100
     
    I like to use the RAM Mfg for looking at what they have tested to work in any MB
