I want to upgrade or build a new from scratch.

I will change the GPU for 3080 or amd big navi (if I can get one of them) and I want to change the CPU for ryzen 3900X (or XT) or the new 5900X, just don't know which one make more sense for this build.

I also think changing the motherboard for new x570 board which about to come out soon as well, just I don't know it worth it or just keep the x470 and wait for AM5 socket.

I am bit concear about the psu if it enough for power all system with the new the GPU and CPU.

Getting Ryzen 5000 + X570 + Radeon 6000 makes more sense because the set can give you better boost with rage mode and direct storage (according to AMD). You won't get this with X470.

25% better performance than 3900x is a no brainer to have it (if you have the budget).

850w should be enough, you don't need to upgrade the PSU.
