I'm also really thinking about selling my second 1080 ti.

It's a ZOTAC Extreme Core. Amazing card, I love it. I have two I use for gaming. One in my machine & my wife's for gaming. Just sold my 3rd, looking to sell my 4th & final Zotac Extreme Core. (Still have the box, even).

It served me well for a year, but I'm done with mining entirely (too much of an upkeep - just had a baby & in/out of the hospital the last month).

I'm still debating keeping it for SLI gaming, but I just ran the Witcher 3 with SLI & get hitching/framedrop issues when I don't with a single 1080 ti. I hate SLI. I hate Crossfire. Always problems & so few games support it. I want to keep it, but at this point... why bother when someone could use it to mine? I loved mining when I had more free time.

I also have my RX 580 & R9 Fury (which I'd also consider selling) but I might keep those for christmas gifting. Idk.
