I am looking to build a new gaming PC so I can move away from console gaming. I want to be able to run AAA games with higher end graphic settings enabled while also still be using youtube. I have a monitor that can support up to 4k, so I would like to utilize that a bit if possible. Also already have a mouse and keyboard. It's the GPUs where I really get tripped up.

Parts from my current build I was thinking of reusing (but totally open to replacing):

-PSU: 650W PSU with 80 PLUS GOLD & 140mm (runs cool, not loud, bought in 2017-2018)

-CPU: AMD Ryzen i5 1600 6core

-RAM: 2x 8GB which seem to be DDR4 (was thinking these could be more like additional or secondary)

-Storage: 2TB M2 SSD

I am purchasing from the US. I would like to keep at or around $1200, but I am willing to go a bit over.
