Professionally done, but where is GTX 980Ti SLI comparison. In the end, GTX 980Ti now Costs as much as GTX 1070. And GTX 980Ti is still widely available in many editions.
No time I'm afraid, in case you missed it .. it's the busiest summer ever with al GFX releases, in order to timely release other articles there is just no time left. I hear ya though - perhaps in a later stage I'll look into a massive mGPU article with different brands and cards all together. No promises though.

Great article - as always! Though I have a feeling something went wrong with "Total War: WARHAMMER" test (or posted result). According to article - in FullHD (1920x1080) SLI works way slower than a single card. Is this correct? 76 FPS (SLI) vs 90 FPS (Single) If this indeed have been the actual test result - a word or 2 on that on the page itself would be helpful.
That behavior is actually described on the conclusion page. Often with multi-GPU solution you can stumble into a bottleneck once you are not GPU bound anymore. The framerates go up higher and higher whereas the graphics driver needs to do it's work twice as hard and thus enforces a much heavier workload on the processor. If that processor cannot keep up you will see negative scaling in lower resolutions, the problem is CPU related and thus a CPU bottleneck.

Thank You Hilbert. I know it is busy time. I have another unreasonable request to ask: "When you are benchmarking RX-480 for FCAT, can you capture GPU utilization and clock over time too?" Even if only for one game, so we can see if performance we see is all RX-480 can deliver. Because at time Fiji released, I measured so many games where GPU utilization was damn low and fps was not great. But with newer drivers, GPU utilization and fps went up. AMD did not recover all there is to Fiji. GPU is still underutilized in many cases. But at least we can get to know if there is untapped potential.
This thread is not at all about RX 480 so please stay on-topic. I'll indulge one reply though, AMD decided not to include a DVI connector (needed) on that card, FCAT is impossible until an AIB partner supplies one with a DVI connector.

As usual, great scaling on GTAV/frostbyte engine games, not so much on the rest. Maybe drivers will improve this, maybe not, but to have the latest DX12 games not support even 2way GPUs is quite a disappointing...

Not impressive at all, probably due to cpu overclock. SLI 1070 means only if u at 4k, only then it match or exceed 60 fps, still not 4k ready though.

Huh? And only at 4k does it match or exceed 60fps? Again, huh? Anyway, nice review HH, some really nice scaling in some games and some not so good but still, this would be my choice if I was at 4k. Much cheaper than 1080 Sli yet capable of 60fps most of the time.
I meant to say that two 1070 seems to match 60 fps or exceed it at 4k, yes in other resolutions too, but i'm talking about 4K now. If u have 4k monitor it seems worth it, if your target fps is around 60, but we far from being 4K ready... i wonder how many years till we get card that cost 200$ and can give at least 60 fps at all games on 4K.

That's quite a selection of relatively untaxing games you have benchmarked. Some more demanding games worthy of these cards would have been great, Rise of the Tomb Raider etc. Especially seeing as the old 2013 Tomb Raider was part of your regular benchmark suite.
I understand that the youtube generation is used to just watching stuff, however this is Guru3D.com and we actually write stuff. How about instead of complaining I may offer the suggestion that you maybe actually read the content, honestly the answer you seek is in there. I'll even go as far as to give you a hint: last page, where I mention Tomb Raider ... twice.

Give it at least 6 more years. And being so cheap another 5-6. It will take more than 10 years for 4K to become mainstream. The hardware and software are not yet ready. (games not optimized for 4K yet, scaling in Windows is simply non existent, hardware is too expensive to become relevant for the average consumer.) People with 4K pc monitors are like what 1%-2% of the total market? We are still long way from 4K to be mainstream.
yep that's why there is no point in going SLI and xfire, not worth the price nor the hassle. But excellent review, i wonder if DX12 games will eliminate cpu bottlenecks and how much time till it happens, i say at least 3 years.

4k 1440p 1080p A refreshing change 🙂 Looks perfect for 144Hz 1440p. Too bad Nvidia still does not support Adaptive Sync over Display Port/HDMI

Never saw the point of SLI. If we had SLI to power games that looked like the Final Fantasy movie then I could understand but just to sqeeze out a few more frames? since games are so p155 poor optimized if they actually made games work on Pc instead of porting them there would be more reasons to go SLI. Specially if they added huge amounts of graphical options to warrent it... Why don't Nvidia and AMD team up to make games for PC?
Point is, CFX / SLI offer performance you can't get on a single card. So if you want to surpass a 1080's or Fury X's power, you need to go multi GPU. If you use the cards for compute power, you'll also make use of it (like folding, SETI, or rendering). If you run high refresh rate displays, you'll need the power. If you run multi display setups (surround gaming), you'll make use of it. And that doesn't change if you run a PC only title...

Sheesh guys, read the full article before asking questions that have already been answered. Great review Hilbert, your benchmarks and information in your posts has always kept me on top of current tech. Thanks to you, I always know what my best buy will be for $$$. Looking forward to the RX480 reviews, and to see what my price point (which video card) I will be getting next.

Great review as always , i see this SLI solution as a budget friendly 4K 60hz 60+fps alternative , that's where it makes perfect sense only in my opinion as 1080p and 1440p seems cpu bound even giving negative SLI scalng. Still SLi and CF it's a hit or miss with games 😏 but right now is the only alternative to run 4K at 60+ fps with all settings maxed out and all the eye candy lit up . Hilbert i have a request ( my first request for you here in 10 years ) , please if you can and if it is possible for you , can you include racing games on your VGA reviews please. I would like to see tittles like Need For Speed 2016 , DiRT Rally etc... on your reviews since there are a lot of us that do a lot of gaming on that genre here in Guru3D. I ( and plenty of audience ) would really really appreciate that. Specifically i'm interested in NFS 2016 SLI and CF scaling as a viable option to run that game at 4k 60+ fps. , that's my little request for you and thank you in advanced. Kind regards: Chispy

Little disappointed with the scaling at 1440p, then again I'm hoping to go 3440*1440 at some point, so should show better gains there!

Everybody's talking about 4k all the time, but the other demanding appication, VR, is developing as well. I wonder if Hilbert is already pondering how Guru3D is going to include that in GPU reviews maybe already next year or in 2018? That might be another viable market for multi-GPU as well as it's even more unforgiving than the usual 2D display, where fps drops already annoy gamers.

someone with gtx 1070 SLI can tell me their graphics score (not total, physics, combined...) in Fire Strike v1.1?. Mine is 32k and want to compare.
Sounds about right, I fortot to make a screenshot otherwise I would have included it but remember it was like 32~33K.
