Greetings ..
now with all benchmark reveal and 1080 hit the market i thinking to upgrade my R9 290 tri-x(@CROSSFIRE) setup to gtx 1080.. OR should wait for gtx 1070 and do SLI config ..i saw those beautiful new bridges... I’m only interesting 4k/60 fps gaming but as i saw from benchmark gtx 1080 cant deliver this..

honestly I own a gtx 1080 it's not nearly as fast as jayz2cents linus tech etc I done my frame rates on steam and didn't get nearly as high as they done the gtx 1080 isn't as fast as the gtx 980 sli as people thought prior to coming out if you're into frame rates then u ought to wait to go with the gtx 1070 or wait even longer to avoid paying the extra 100 dollar charges like they done with the gtx 1080

A GTX 1080, from recent reviews, looks like it has difficulty maintaining 4k AND max settings on modern titles, ussually with a frame rate right in the 50-60 fps range. Some light overclocking and you should be good. That said, many of the reviews show some demanding games struggle to even run at 40 fps on a 1080, max settings, of course.

The more important question is whether you can get a better machine from 2 1070s in sli. I could not find any benchmarks online, so I don't know for sure, but I can give the following cursory analysis:

The 1070 has about 3/4 the cores of the 1080, and a similar ratio for memory bandwidth. If it scaled perfectly, you could expect a %50 percent improvement out of the sli. Unfortunately, scaling does not work that way. In fact, if I remember correctly, the 1080 is only about 20% faster then the 1070, while perfect scaling would predict around 30%. Recently scaling for sli has been pretty good, around 70 percent, which would give you a faster machine then a 1080.

You have a decent graphics set up, you can sweat it out a couple weeks. Get it, sweat it out, since you have an r9 290?

I believe yes, because if a single 1080 is faster than 2 980's in sli, then mathematically 2 gtx 1070's will absolutely stomp one 1080, because the 1070 singularly is 2x better than its previous iteration the 970 so yeah 2 1070's for the price of one 1080 is a good choice IMO.

Update: I will be personally upgrading from a Gtx 960 to the 1070 so if anyone wants to know if the 1070 is a piece of shit, I will be happy to let you know!

I even went on valley benchmarks to see what my frame count would be even though i'm on 4k , I had 1440p with 2 gtx 970s in sli and gotten 144 frame rates, on my 4k I was only getting 30-50 with the gtx 1080 so it should tell u it's not as fast as other people were thinking

I’ve done some estimates with various youtube GTX 1080 and 1070 reviews. If we base this on the founder’s edition cards this is what ive been able to put together so far please take it that this is an estimate generated from 25 game comparisons on the gtx 1080 and 1070.

First Single cards 1070 vs 1080
1080p:- the gtx 1080 is 17% faster than the 1070
1440p:- the gtx 1080 is 20% faster than the 1070
4k:- the gtx 1080 is 22% faster than the 1070

Now to answer the question is 2 gtx 1070s better than 1 gtx 1080 this is based on only “one” game that I could find duel card 1070 setup running witcher 3. It showed a 43% increase from a single gtx 1070 to an sli 1070.

So 25 games run on a single gtx 1070 add 43% and look for the average looks like gtx 1070 in sli is 18% faster than a gtx 1080 for 22% more money than a single gtx 1080 founder edition.

This is a “guess” but it’s not a number plucked from thin air it’s based on real data from what little is available so far.

Id say that 2 gtx 1080s over clocked in witcher 3 wouldn't guarantee that 60fps on 4k consistently through the entire game with everything turned up to max.

I am looking to get 2 1070s when there out. Although with the lower power needs of the gtx 1080 compered to the gtx 980 ive a sneaking suspicion they are going to bring out a gtx 1090 and a low price 1060.

A single 1080 will have a higher resale value than the cost of a 1070 today when the 1080 ti is released. You'd be better off getting 2 1080s now and reselling them when you upgrade. Considering we are starting to see 1440P 144hz monitors become cheaper and already have 4K wide screen IPS 34" in the $1200 range that can take an OC of 100hz, a 1070 sli or 1080 sli setup is still not future proof for a few years whereas the 1080 ti SLI may be if it is a good 30% faster. With gsynch, 144hz 4K is the forseeable endgame for display technology and we are at the point something can at least manage it with plenty of room to grow. Same basic premise for VR. If you only upgrade every few years, then we are not quite at the point of a next generation system, but by Christmas we should be there.

demoth u will be wasting money as a lot have done with gaming on 4k monitors , wasn't getting anywhere a constant 60 frames per sec on the new games but honestly be better off waiting for a 3-5 yrs as graphic cards become more powerful and efficient cooling to run properly

on my games I was getting upper 20s to 30s frame rates on 4k , this is on a 60 hz , try 144 hz, you're in for seriously bad results , as I seen on jayz2cents benchmark getting over 100 frames per sec on 4k , if anyone interested in 4k and wants to try the gtx 1080 look up openbox something on youtube his benchmarks is as close on white on rice with mine no where near the others , my set up is a 4790 processor, 32 gigs of memory with the gtx 1080

Sorry, but lets not forget there are custom pcb's and coolers out there that are easily going to hit 2.0GHz with some mild overclocking and still run nice and cool, so my best guess is for the price of one founders edition gtx 1080 you could buy 2 gtx 1070 custom cards and probably by my estimate run a semi solid 60 fps at 4k, this being said wait until it releases bc you are not going to be able to get one at launch most likely anyway so wait for benchmarks and then make your decision.

There is no easy answer for your question.

There are titles that cant even use SLI, so that would be a bummer.
On the other hand, 1070 SLI should strongly outperform 1080 if it scales well.
http://www.guru3d.com/articles_pages/geforce_gtx_1080_2_way_sli_review,13.html

Read that page and forward.
As it seems, 2 SLI gives a fairly huge jump in 1080s, so assuming 1070s are similar, youd expect higher average frame rates from SLI 1070 (and of course this is an assumption).

Bare in mind however, that minimum frame rates are much more important than average frame rates and from what I have seen, SLI tends to have more problems with minimum frame rates than single cards (this is a very strong generalization, so dont take it as a rock solid statement).

Over all, if maxing all details, it seems that even 1080s in SLI will have some problems with 4K in the most demanding games, but it also seems that even a single 1070 can mange 4K in the less demanding titles.

Personally I used both SLI and crossfire in the past and due to mixed results I now stay to the most expensive single card that I can afford (in my case, a single 1070, for 1080p gaming).

the most expensive doesn't mean they're the best , as to my 2 gtx 970s I had in sli were a lot faster than the single gtx 1080 , and NVidia claiming that the gtx 1080 is faster than 2 gtx 980s in sli , in my case I found inaccurate b/c I had a stable 60 frames with the gtx 070s than I will with the gtx 1080 the only difference is 2 extra gigs of vram

that is in 4k resolution ,, even though I tried both 2560x1440 p with 144 hz and 4 k didn't get nearly 50 frames in 4k that will tell u that your frames will drop dramatically in 144 hz 1 of the reasons I added another gtx 970 into sli in the 1st place with the 144 hz

I've been reading and watching others and you'll see who is sponsored by NVidia or amd to promote their cards and those who aren't, like jayz and linus tech who are sponsored by NVidia and amd to promote the cards saying and manipulating their screens and gameplay to think it's as good as NVidia or amd says as later times came out seen more that aren't sponsored by either showing the real results , I've spent countless hrs watching the competition with amd and NVidia thesecards aren't nearly as good as they claim

Scaling is actually much much better than ever. I get 100% scaling in GPU heavy workloads. Witcher 3 a prime example. I'm going 1070 SLI and trading up from 970 SLI. SLI haters are everywhere, but most of them have never used it.

Nvidia is dominant in the upper end and when the 1060 hits, upper mid tier. Not only (should/does) 1080/1070 SLI even better with the $25 add-on bridge, but the 1070 draws less power at stock than a stock mid range card from generations ago and nowhere near the Titan X or even the 970 which it beats in every way. In fact, 2 1070s SLI should finally represent entry level for a 75hz+ gsync 4K monitor and even questionable PSUs can run them. Yes, you'd be at that 40-60 fps sweet spot for gsync but room to upgrade cards in a few generations without needing a new screen too soon. Plus much less strain and heat for the system overall.

However, gsync is where Nvidia may also ultimately lose. As the market floods with high quality (panels) with offbrand names with 1440P and 4K 30+" screens under $300 that all have freesync thrown in while gsync equivalents have a $200 premium, the 480s look like an attractive stopgap and then a strong leaning to a future AMD upgrade. Be aware, brands like atron vision already have IPS 1440Ps under $300 that OC past 160 Hz and next release everything not specifically made gsync will be defaulted freesync due to no double charge system Nvidia adopted.

gtx 1070 is a decent card for running on 1080 p or 1440 p but it's not recommended for 4 k gtx 1080 is the 4k flagship card but as for demoth's comment if you go with a freesync monitor you will need to have a amd card as well with gsync monitors for NVidia , I tried to cross a amd card for a gsync monitor and gotten 120 hz where I should of gotten 144 hz , as with the gtx 1080 there was doubts that it wasn't nearly as fast as the titan xs but as drivers been released it's changing , and the yahoo sites can't go by what jayz2cents , linus tech as well as a few others on there , they will mislead you to think it's faster than it really is ,like a lot of cards got to give it time to have drivers etc released

I'll be finding this out personally next week. Parts come in wed. I went and ordered x2 MSI gtx 1070s gamerx fac OC gpus with the new evga sli hb bridge pushing off a Intel i7 skylake 4.0 quad with a corsair h105 cooler. Hopefully I'll be able to give you guys some positive feedback. I ordered a AROC 28" 4k 60hz monitor and a Asus Swift 27" 2K 144hz monitor. Ill let you know how the bench tests turn out.
