CPU's have been grossly outperforming GPU's, RAM, storage devices and all kinds of buses and connections ever since they went multi-core. I never strained my old i5 past 45% for gaming, but I bought a new one anyway since my old one didn't fit the motherboard that I needed for my GPU and memory.
Intel processors are magnificent, never had any trouble with them either, through my 12 years or so of using them, and they overclock really well as a bonus!
