Gtx 1080 Sli question

[IrishDunner]

I'm a new pc builder, I have a gigabyte G1 1080 is there and what are the advantages to running dual cards 

 

Thanks

On certain games you get a great performance improvement on the big majority of games SLI just causes issues

 

Cons: Heat, Power usage, very pricey for little improvement

 

It would be handy if the VRam would stack but sadly they dont

[Peskanova]

Its not close as double performance , almost 50% but not double (its not recomended bang for buck wise)

There you go man, enjoy the read ;-)

Certain games do use SLi set ups but the problem is they don't tend to scale in performance especially for what you pay for an extra 1080. If your chasing benchmark records as an example these synthetic benchmarks work amazingly well with multi GPU setups. Personally I would always go for 1 powerful card over multi GPU setups. IMHO

Most games today aren't going to benefit from SLI as they don't scale well. You would get better performance in rendering, but in games, it is not worth it. You do need more power and more heat, and cards that are placed together, might overheat and have a lower life time.

All of my games perform better. Maybe not something old like command and conquer but that’s not a hard game to run. 

 

I can only rub both 1080’s on one game right now and that’s pubg. Cpu can’t keep up in anything else. But I would need two to get the frames I want in 1440p or surround 1080p.

OP just look what games you play up on youtube with SLI. Most ppl here slam sli,so you will get a in accurate answer, its usually per person type of situation, so look it up from ppl who are doing it themselves. it is ytrue you dont get double performance, but if your only using 1080p its not worth it. 2 1080's in sli is good for driver higher settings and fps in higher res especially 4k.

[Frankenburger]

Statistically speaking, when SLI scales, it scales by about 70% on average. Also, there are games out there that have 90% scaling, but there are also games out there that have no scaling. Whether or not SLI will benefit you will depend on the games you play, and if you're willing to use Nvidia Inspector to tweak your drivers. If you're fluent with modding games, you enjoy tweaking settings, or prefer super sampling, you'll find that the added performance of SLI will be extremely helpful. GTX 1080 SLI should easily let you reach 5120x2880 in most games with playable frame rates.

Well I have a 4k g-sync monitor

I have a 1080 SLI setup. I haven't had any issues in any games that I have played. Scaling is dependent on the game but I've seen at much as a 93% performance increase. Dealing with the heat is always an issue with SLI setups. I watercool so it in'st as big of a deal but be prepared. If you are running a 4k monitor the extra pixel power will be noticed. I run a 1440p 165hz display and felt like the single 1080 wasn't enough.
