Quick answer
What is the decision in one sentence?
The RTX 5090 and Ryzen 9 9950X3D make sense when one machine has to be both an elite gaming PC and a heavy creator workstation. AMD lists 16 cores and 32 threads with boost up to 5.7GHz, so cooling, motherboard power delivery and PSU headroom matter more under long mixed workloads than they do in a gaming-only configuration.
