The last time I built a PC was around a decade ago but I always bought AMD simply because they were cheaper for equivalent performance in the middle. Getting an adequate CPU for hundreds of dollars cheaper than the higher-end Intel chips meant that I could afford the second-highest-end GPU that NVidia had at the time. This made a lot more sense for gaming workloads as $300 towards the GPU had a much bigger effect on frame rate than $300 towards the CPU.

These days iGPUs run pretty much any game I care to play so it doesn't matter.
