Upgrade hint

Hey, guys. 

I actually have a 5600x 32g ram 3600 and a 6700xt 12gb vram.

After premieres's last upgrade, I felt it a bit heavier to my system.

What upgrade would you guys choose? 

1. Upgrade CPU to 9900x and keep the 6700xt;

2. Upgrade both CPU to 5900xt and GPU to a 7900xtx;

Or, still:

3. Keep the CPU and upgrade GPU to the 7900xtx.

I just use it for premiere, editing in 4k slog 8bit and for obs in lives. Sometimes, gaming in 4k.
