best gpu for triple monitor setup?

[Juniiii]

I currently have this build

 

Ryzen 5 1600

24gb ram 2x8+2x4 2400mhz

RX 580 8GB

 

I have 3 monitors and the RX 580 holds up pretty well with gaming on all three like 70% of the time, and the other 30% is when it gets heavy, and it starts to become jumpy. I have a budget of $300 on the GPU and I'm planning to get the R5 3600 soon as well. I'm thinking of going Nvidia for the card since I haven't been very happy with the 580. I'm like on the line between the rtx 2060 and the gtx 1070ti, I'm more than happy to buy used cards as well, I wanna get the rtx 2070 but would it be worth it??? please help im scared to make a decision

If it is between the 2060 and 1070ti get the 1070ti, it has 2GB more VRAM allowing it to better handle the higher increased resolution of a triple monitor setup, after that I would recommend 5700xt (no seriously this card is a really, really good deal in the US), and then maybe the 2070 super. With 3 monitors you are going to want to get as much GPU power as physically possible, so from the sounds of it I would probably have to recommend either the 1070 ti or 5700 xt.

nah i hate amd cards, I love their CPUs but the GPUs are far from being decent
