Hello, i'm running on a 1440p 144hz monitor and i'm looking to purchase 2 1080s, i wanted to know if microstutter is still a thing, also what benefits and what problems will come along with it? i've heard alot of good things about SLI and alot of bad.

I will be gettings 2 1080s from a friend, he wants to sell them both to me for $650, would this be worth the SLI?

I wanted to know your opinion!

Thank you!

I7 8700K

650W Gold PSU

CF/SLI configs have always been very game dependent. The problem is most games aren't being setup for SLI. It can work, but the main issue I see now is the scaling is bad. If one 1080 gets you 100FPS, it would be nice if the second got you 180 or 190FPS right? Is 140FPS still worth it? SLI used to be needed to 60FPS with larger resolutions. Now we have cards that for the most part handle them. A 1060 can mostly hit 60FPS at 1080 with details up. Not maxed, but it will look good. The 1080/TI can mostly handle 4K. And that's a single card.

Assuming there is nothing wrong with the cards, I'd take that deal. You should be able to use one, and sell the other for $300-$350. And ~$300 for a 1080 isn't a bad deal at all. I'm not...

I'm not sure I'd try to run both 1080s on a 650W. The 1080 is rated at ~200W each, so two together would be 400W just for the cards. You are looking at around another 100W for the CPU, and then more for the rest of your system. That SLI config would be around 550W all together. That's 85% output on a 650W PSU. My rule is to not go above 80%. Depending on which 650W you have it might not even have the plugs needed to run both cards. It should handle a single 1080 just fine though.

Pros
-The games that do support it can scale quite well.
-Looks awesome!

Cons
-Lack of driver support, in some cases you can actually get worse performance in SLI compared to a single GPU.
-Heat.
-Power consumption.


What I'd do. Buy one if possible or buy both and sell one.
