If you’re building on AM4 and want the best gaming experience without going AM5, the 5800X3D is the obvious choice its extra L3 cache makes a noticeable difference in FPS-bound games. For pure productivity (rendering, editing, streaming while gaming) the 5900X/5950X or even a plain 5800X will beat the 3D chip because they have higher sustained clocks and more threads. My rule of thumb: gaming first → 5800X3D, mixed heavy productivity → 5900X, strict budget → 5600X/5600G.
