Why This Bottleneck Occurs
At 4k resolution for gaming, the NVIDIA GeForce GTX 780 creates a minimal bottleneck (2%) when paired with the Intel Core i7-8700K. The GPU cannot render frames fast enough to match the CPU's throughput capability. At 4K, the GPU is under extreme load rendering 4x the pixels of 1080p, making it the clear limiting factor.
