GTX 970 SLI vs. GTX 1080

[Psynatron]

Been waiting a long time for the new Nvidia GPU, and i just got my paycheck,

but i cant really figure out if i should get the GTX 1080.
atm. i got 2x GTX 970 SLI.

Is it worth to upgrade?
$900 for how much more performance? (Im from Denmark = 25% tax)

My GPU's are 2x ASUS Strix
And i want to get the ASUS Strix GTX 1080

Im using Asus 27" LED G-Sync Rog Swift PG279Q monitor with 2560x1440 and 165hz.

Im kind of tired of the SLI thing. It dosnt support all games, its heating more, and it pretty often turns itseff off. :s

Look a single card is always a better solution than two. As you know there are a lot of problems with different titles and sli configs. The power consumption will be much better, as the overall noise (under load). The big downside of upgrading to a 1080 is the hit you are going to take since the 970 prices have plummeted with new ones going for 250 euros in germany (not the strix ). So if you want to sell them it is going to be quite cheap.

Personally i would suggest waiting for the prices to drop a bit. I believe that when some of the stock 9xx series is sold the prices on 10xx should go down. Also AMD's 480 should drive the market into a better place. Of course, the same applies for the used market . 900 euros is quite the price for a single card. Also take a look at mindfactory or computeruniverse if you haven't already.

atm the 970 sli is in between the performance of 980 ti and 1080. unless your games run on more vram or you have issues with sli. I personally would not upgrade until 1080ti or the new titan (if they ever make one).

When you say that it turns itself off, did you mean that SLI mode gets disabled or do you mean the entire system turns off/crashes? I have exactly the same cards that you do in an SLI setup, with a 1440p monitor, and I have yet to have any problems with games being compatible/being able to force SLI to work. I also have no heat issues, even without air conditioning in my house. I do have a water cooler on the CPU, though.

I sometimes have issues with SLI turning off if I turn on windowed mode on a game; SLI doesn't work in windowed mode, and when you re-enable fullscreen you have to sometimes manually re-enable SLI from the Nvidia control panel. I can remember having some trouble with SLI when I had an AMD cpu, but I've since built a new Intel system and have had no more problems that I can recall.

Regarding game performance: We know from various benchmarks that the GTX 970 SLI performance is comparable to the GTX 980ti, depending on the game (and the CPU, of course). The difference between the GTX 980ti and the GTX 1080 can be seen there. There seems to be a significant performance increase with DX12 games, but whether or not you consider that to be $900 worth of a performance increase is up to you. I personally have my eye on 4k as my next jump, and the 1080 just isn't cutting it, especially at its current price. Once AMD releases their next cards and once the holidays roll around, the prices should drop to something a bit more reasonable relative to performance.

Even 1070 will perform slightly better and much more consistently than 2x970 in sli.
Check the reviews of the games you like to play and see the numbers.
1080 is a great card for 1440p gaming.
1070 is just a good card for 1440p gaming

Well 980sli = Gtx1080 +10% .970sli = titan x +15% . Gtx 1080 =titan x +25% .so the actual performance you will get is small but you will max out all games and play at 4k without sli only with a single card(don't buy the founders editon) also NVIDIA is using new software on the new 10x0 and they support better the dx12 than the 970 .so I would sell the 970 s and buy a 1080.
