Is sli worth it?

Hi and welcome to TSG.

I would try things with just the 1060 and see if you are happy with the graphics; if not you could go for SLI then.

 

Gulo is correct about your motherboard has to support SLI.

A few years ago, I went crazy and did SLI on two different generations of Nvidia GPUs. What I've found is in the end it wasn't worth it for me. For the gaming I did and do now, it's just not worth the headaches and issues. First, you're going to deal with a lot of heat being pumped out the back of your PC case. This heat is also going to eventually cause reliability issues with the GPUs. Both SLI setups eventually resulted in failed GPUs. Next is system stability issues. I experienced too many system crashes for my tastes.

So my philosophy now is to buy the most powerful GPU I can afford stretching the budget and then calling it quits. If the GPU starts to falter due to the games I'm playing, then I'll just upgrade the GPU at that time. I'm not a pro gamer nor do I run crazy resolutions on multiple screens with a bunch of stuff turned on looking for the highest FPS. This logic has served me well as I haven't touched my gaming PC in years other than upgrading the SSD storage in it.
