Jonathan's son wants to graduate from a Nintendo Switch to a gaming desktop. He loves Fortnite. Leo recommends the Asus Republic of Gamers (ROG) system. He bought that for his son not too long ago. Leo also likes the Lenovo Legion. You want to focus more on what your graphics GPU is over the computer CPU. That will do the heavy lifting. And the models they offer at Costco are likely last year's models, ideal for a budget gaming computer. But still doable. You'll want a 60fps system.
