Is it worth it to get a pc?

Hi guys could someone please help me decide if is should get a pc?

So I’ve got around 800USD to spend on a PC but the thing is i have a Xbox series X, I play Fortnite FIFA and Roblox and was wondering if it would be worth it to spend my 800 dollars on a pc? Would you guys do it? Also if I’ve already got the peripherals and everything just the PC
