I'm planning to build a new gaming PC around the NVIDIA RTX 4090 GPU. From the specs, it looks like an absolute beast for 4K gaming.

My question is - what CPU would you recommend to pair with the 4090 to avoid bottlenecks and maximize performance? I'm considering the Intel Core i9-14900K or AMD Ryzen 9 7950X3D. Would either of those be good choices?

Also, is a high-end CPU even necessary with a GPU as powerful as the 4090?

Any advice on CPU selection would be much appreciated before I start purchasing components.
