I want to get into mining, can you help?

So I have a few rigs that sit around the house all day some powered up others just
waiting to turn into trash. What I want to know is if it is still worth mining Bit coin with
a 1080TI video card or am I looking at this the wrong way.

If you can help PLEASE do.

EDIT:
I would like to use my current equipment but I guess I need to also know like do I need fast Internet? my rig cost me about $100 in electricity a month, can I out mine that much?
