350 euro ready Pc?

I need a 350 euro ready pc where I can play Fortnite with normal graphics and 60 FpS + GTA 5 should be smooth thanks in advance

I would be surprised if something like that is possible. The best thing to do is to get a Ps4

For 300 a finished PC? That is already very cheap and then also claims.
It will not work like that.
At most you can have a look at Ebay, but otherwise you will have to keep saving.
