Advice about second GPU

I'm mining raven for a while now with one Asus rog strix RTX2070. Right now i'm getting 19MH/s which results in around 20 coins a day on a good day.

How much of a pain is it to install a second, better GPU? Was thinking about buying an Asus 3060 ti.

I have to install drivers for both, i heard the order might matter.

I can then edit the command file and associate a GPU. Run 2 instances of my favorite miner and voila.

Is my power supply good? I think so since i'm running at 230 watt right now.

Is that it? Is Windows oke with all that this easily? I heard about hiveos, i could dual boot that because i still sometimes want to use my computer, shame on me. Is it all that easy or should i know things?

Setup :

MOBO : Asus ROG STRIX X470-F Gaming

CPU : AMD Ryzen 5 2600X

PSU : EVGA Supernova 850 G3

GPU : ASUS ROG-STRIX-RTX2070-O8G-GAMING

RAM : G.Skill Trident Z RGB DDR4 16GB

Everything air cooled.

Just asking advice before i throw money at this. Thank you.
