will this dock work with evga nvidia 1070 graphics card?

I understand that if it should work, I tested it with an nvidia 3060 and it worked fine.

Can this connect to a Lenovo legion y520's Pci slot ?

Yes, but the power supply must be a PCI-E interface.

how can I connect this to a laptop with thunderbolt 3?

You would have to take the "data express cable" and remove your WiFi card in your laptop, then take that cable and insert it into the slot where the wifi card was.

Will my graphics gard performance be limited by using this set up? Also is a regular DC 12v power supply sufficient?

Hello, Please tell me what graphics card you use. Regular DC 12v power supply is sufficient.
