evga gtx 1080 sc sli???

[jesselav1233]

I'm currently using a i7-6700k and a EVGA GTX 1080 SC. my motherboard supports SLI. I'm wondering if anyone on here is currently using 1080s in SLI and if they think its worth it for me to upgrade? My one 1080 does 1440p maxed out on most games but I would like to be able to play in full 4k do you think if i get the other card i could do that?

There are certain advantages of SLI that such a configuration could reap:
1) Higher maximum framerate.
2) Higher average framerate.
3) Bragging rights.

There are many disadvantages to SLI that you may run into:
1) Power consumption and heat output. Is your power supply capable of powering two 1080's? Does your case have good cooling?
2) Lower minimum framerate in many games.
3) Support. Does your motherboard support SLI? Do your games support SLI? If these are not both met, only one GPU will be used.
4) Microstutter. Thanks to the bridge and PCIe lanes between the cards, there's a delay in the communications between the cards. This means that even though you may achieve a higher framerate, your games might not play quite as smooth as they do with a single card.
5) CPU Usage. Having two cards means twice the amount of work the CPU has to do to keep up. If your CPU can't keep up, additional stutter will be introduced on top of the microstutter from the bridge/slots.

Please list full system specs. Be specific, include make and model of your power supply.

mobo-MSI Z170A SLI plus
CPU-i7-6700k (corsair liquid cooled and oced to 4.5)
power supply- corsair RM750x (gold rate)
RAM-Gskill (3200)
case-Corsair Graphite Series 780T Full Tower PC
I will get the corsair 1000w gold rated if i go SLI just because I OC and have 3 hard drives.

Actually 850w should be plenty. Go for RMx or RMi (these ones are newer designs). The original RM series uses lower quality caps. If the price difference is low where you live, then I can say to go ahead and get the 1000w, but if it's expensive in your area then just go for the 850w.

What's your CPU liquid cooler? Is it exhaust, or is it intake? We need to take into consideration that a second card will introduce more heat into the airflow within the case, and I want to make sure it's not going to overwhelm your CPU cooler.

cooler is Corsair Hydro Series H100i v2 Extreme Performance Liquid CPU Cooler i set it up as intake because thats what corsair says to do on the instructions.

I guess my real question is will it run 4k maxed out and maintain 60 fps? I think i should be able to deal with the heat fro the cards although i kinda wish i got blower style but its to late for that now.

If all you're looking for is 4K60, try using Med-High settings and tuning the individual settings from there. Using Very High or Max settings usually stacks on a bunch of AA and post-processing effects that you can't even see. I don't recommend AA settings higher than 4x if you're looking for performance.

Things that can be turned down to improve FPS without dramatically hurting the visuals: AA, post-processing, reflection quality, shadow quality, motion blur, water effects like Advanced Shore, hair effects like Hair Works, render distance, etc.

If this gets you the FPS you want, then there won't be a need for a second card, right?

yeah but i got to have that ultra settings cant spend all this money and play on med-high settings lol.

A second card will only help you in games that support SLI. I've told you what you need for your setup (a power supply), and now it's your decision.

However, do you know the GTX 1080 ti is out now? If you can afford it, it's much more powerful than the 1080 and doesn't include the drawbacks of SLI.

 

[jesselav1233]

I know wish i waited and got it that's why I'm contemplating doing the sli plus my board supports it because i had 2 970s in here before i got the 1080

I actually have the same card 1080sc i play all mt games in 4k 60fps for most games. Some games like Ark and Witcher 3 wont get full 60fps off one card, so im gonna eventually SLI 2 1080ti's. I also mistakenly got a 4k monitor with freesync as gsync was too expensive. Though I get some tear because I cant use Gsync.I still get a crisp beautiful almost photorealistic landscapes and graphics. But you can pusk 4k, and even get high 30's 40's and 50's on some taxing games...4k is still relatively new so optimizing will be coming, and things will get better. But the 1080ti is the way to go, if you can't wait for the next gen cards like Gtx 2080 or 1180 whatever they will be. There are also lots of settings u can turn off thru Nvidia control panel, Like Resolution scaling. 4k monitors dont need it. It's doin double the scaling for no reason. I know its a late response, but I only got to PC in mar, so I just found this post looking to see if a 1080sc can SLI a 1080ftw for now.
