Usually trying to defend a difficult position with "watch this video" is simply a case of digging your hole even deeper."
Sure, you can make that claim. Now, run an older game, attach that system to a 4K monitor, and run at 4K resolution with the details cranked up. Suddenly it's not the GPU anymore.
Bottleneck calculators, and a CPU-to-GPU correspondence/match concept, are garbage.
I listed the three things that are the considerations for picking a GPU - don't keep trying to justify a "this CPU with that GPU" methodology. That is not accurate, nor helpful.
