What kind of GPU could I use to get stable FPS with max reflections?

Title says it all. I currently have a Ryzen 5 1600 Six-Core and a 4GB RX 560 with 8GB RAM.
If I got an RX 580 or even an Nvidia 1660 Ti, would those be sufficent to be able to max reflections? I'm talking distance, detail, update rate, resolution, etc.

 

Yeah

 

Well I mean obviously it'd depend on the map and stuff too. Let's take vanilla maps, and maps like Italy?
Obviously doubt I could do it on American Roads or Los Injurus.

 

Both of these are only hard on the ram the hardest map to run for the gpu is italy
