Need your advice for a rig

Hi guys, I started farming 3 months ago through Chia and recently I got a 3070ti to start my gpu mining adventure specially for rvn.

I'm thinking to do a PowerPoint to convince my wife so I can build a decent Gpu farm for rvn 🙂

Whats your experience so far? I like the 3070ti comparing price vs profit.

Here in Portugal is costs 850 eur and produces around 100 eur net after electricity.

Was thinking maybe to build 2 rigs of 4/5 gpus each.

Let me know what's your advice, right now my 3070ti does 40mh and consumes 265w.

Cheers Zooky
