Tips when installing a AMD GPU

Specifically if it’s a RX 580.

Is there any I need to know that your be hasn’t told me?

I’ve installed a lot of Nvidia cards and is it the same as a AMD card?

Is there any software I need to download when I install it?

What are things to expect when you plug it in?

What if it has a 6 pin connector but the card has a 8 pin but it comes with a 6pin to 8pin?

Any recommendations or tips outside of these is only wanted.
