How should a GPU be paired with Ryzen 9 9950X3D for 1080p, 1440p, and 4K gaming?

  The Ryzen 9 9950X3D is 16 cores and 32 threads on Zen 5, AM5 platform, 4.3GHz base and 5.7GHz boost, 128MB L3 (single-CCD 3D V-Cache), 170W TDP, launched March 2025. X3D's value concentrates at high-refresh 1080p and CPU-sensitive titles; at 1440p and 4K the bottleneck shifts to the GPU and the CPU advantage fades.

  Pair the GPU by resolution: for high-refresh 1080p esports, a mid-to-upper-mid card fully uses the 128MB cache; at 1440p go upper-mid; at 4K put the budget into GPU and VRAM, where the CPU barely affects frames. Build on AM5 with dual-channel DDR5, and pick the GPU by full model and cooling — laptop TGP talk doesn't apply.
