Never skimp on the PSU (Power Supply Unit) quality, never ever.
Also the motherboard, as it does a lot of power regulation. Important if you're going to run the system hard. He can probably go cheap on RAM though, and the CPU for that matter because games are mostly GPU limited these days (Dwarf Fortress excepted).
Depends on what you play. IDK what a Elden Ring is, but I wouldn't assume anything by it anyways. Strategy games tend to chew a lot of CPU and be poorly multi-threaded.
Elden Ring is a jap RPG. But yeah, Civ and Total War games are a bit more demanding on the CPU. I'm not saying buy a cheapo i3, just that a midrange CPU is plenty for most games these days. He should spend more on the graphics card than the CPU.
