It’s clear that GPUs are improving rapidly compared to CPUs. Whether a more powerful GPU needs a more capable CPU depends on your goals—aiming for 60 FPS means you’ll want enough processing power to handle the game’s demands without the CPU becoming a limiting factor.
GPUs can run efficiently for extended periods before needing significant system upgrades. Eventually, a powerful CPU might be necessary to fully utilize their capabilities. However, this isn't likely to happen soon since CPUs are improving rapidly enough to avoid such limitations.
CPU performance for 1080p and 4K is similar, but GPUs offer much higher efficiency. Even if CPU improvements stall, we can still tap into more GPU power. AA tasks are heavily GPU-dependent while the CPU remains unaffected. Using low-level APIs also helps lessen CPU workload.
Higher resolution raises the GPU's performance needs while having almost no effect on the CPU. If CPU speeds remain steady and GPUs become four times faster, running at 8K won’t cause CPU problems.
Many folks overstate the situation with "bottleneck." In reality, the CPU usually struggles only when exceeding 60 FPS, so unless you're using a very slow processor that actually limits performance, you won't need to worry. Unless your system is extremely outdated and underpowered, which would hinder reaching 60 FPS, the opposite is true. As resolution keeps rising, the GPU has to handle more work, often becoming the limiting factor. Therefore, my take is NO—modern CPUs are sufficient for now and should handle future upgrades well, even with faster GPUs.
Latest i7 and now R7 chips will cover the top-end GPU selections.
I should probably clarify this more clearly. For a CPU running at 1080p60, it’s essentially the same as 4K60 in terms of workload. But when you lower the resolution, the GPU’s load decreases, which boosts FPS and increases CPU demand since the GPU bottleneck is lessened. Imagine an unlimited GPU with a CPU that can handle 1080p60. Raising the resolution to 4K usually lets the CPU maintain around 60 FPS or close to it. Adding extra work to the GPU won’t change much because performance depends heavily on GPU capabilities.
