you better off getting a console, they are cheaper but it cant do as much as a pc, in terms of multi purpose device.
if you wanna go pc gaming just go for $1000 gaming rig future proof will beat nextgen console.
if you looking for a $400 price tag, you will most likely get a rig without OS, without wireless network cards, without dedicated graphics, bad motherboard not future proof etc. Sellers will put that in small print, you will most like not get a full package ready to play.
I not saying that PC is worse...it just costs more takes more effort to achieve that greater gaming potential. --- "Nothing is impossible when you have complete control of the environment..."
