Need PC Recommendations

Hello! I’m a college student on a budget of around $1,250 looking for a PC to game on/ stream. I’ve been on console for forever and wanted to switch it up.

I know nothing about PCs but all I want to be able to do is play games at good quality graphics in the 120-240 fps range. I mainly play Fortnite, but also play other games.

On top of all this I’m an engineering student so also something good enough for just casual work.

Recommendations could be pre-built or parts!!

Thank you so much in advance!
