Is SLI stable?

[R3DOPS]

I herd in the past that NVIDIA SLI is not as stable for most games. resulting in disabling SLI. Or that most game do not support SLI so the extra GPU is not being used. I currently have a gtx 1070 FTW. I want to run 4k ultra 60FPU up and VR stuff too. I also plan on video game development as that is what im taking for school and such. So my question is, is it worth getting another 1070 ftw in sli? or selling the 1070 and buying a 1080ti or just 1080?

SLI Is highly reliant on support from developers which is basically non-existent these days. The performance of a 1080 versus 2 1070s is better just given the fact that SLI isn't supported much.

 

You can find tons of threads here describing the issue with SLI on here.

Nvidia is in the process of nerfing SLI. In the past (7xx series cards) I had never had trouble with it in any games, and had great success forcing SLI on applications through the driver using "alternate frame 1" or "alternate frame 2" options. However, I have heard many people say that it's more work or that it's unstable.

Newer cards are very game dependent as to how much SLI will help, or if it is even supported. Older cards (from the era when SLI was being pushed) will have better support for it in the drivers. However, YMMV.

There's also the issue of micro-stuttering which while both companies acknowledge, don't seem to put any effort in minimizing it to almost none.

 

Or maybe that's just me having old information.
