I have 2 decent GPUs I bought before they all surged in price and I still don't think it's worth it. Really feels like you need a rig with 5 GPUs in it or something. I even looked up Burstcoin and I have 20TB and it's still not enough profit, IMO. You still need at least 50TB to make an okay return. Mining in itself it's just too inaccessible for people who can't afford the hardware.
