Apparently you can use a $75 crypto mining GPU without a video output by connecting it to your main GPU and using a modified driver!

The GP106-100, a 6gb geforce GTX 1060 without the display ports, can be used within your system apparently, according to Linus Tech Tips.

I watched these videos when they were first uploaded, and I'm not sure how well they work with cycles, however I just bought 2 of them so I will update when I get them working on my linux render server.
Thanks for trying this out and sharing how it goes. I look forward to hearing the results!
Oh my god buy like 5 of these right now!
It was so easy to set up, especially if you already have a graphics card. I put one of these next to my GTX 1070 and I didn't have to do any hacking or ANYTHING! There was an error the first time I started my computer after installing, but after a reboot everything worked fine, all I had to do was check the box to enable it in the preferences. This was installed in my main rig which I actually work on, so I was surprised at how easy it was.
Warning though, shipping from China is murder. I ordered 2 cards and it cost me $50 in shipping at the cheapest option, so just be weary. Both cards were still cheaper than one 1060, so I still consider it a deal, but it pushed the budget a little.
Also the cards don't have any mounting, so they don't support themselves well. Luckily the one in my main rig is close to the bottom so I used some corks to lift it up, and my headless server that I plan to install these in horizontal so it shouldn't be a problem, but food for though. I see some screw holes in the card, so it might be possible to make your own mount.
No need to use modified drivers. These cards will work with blender natively.

Yep, you only need to modify drivers if you want to game on them. Had 2 of these in a render server rig and it was the best business investment I think I ever made
