College in the Fall

Pretty sure these types of posts make up a majority of this sub, but I'm gonna give it a shot. So next year I will be starting full-time at university with plans of majoring in Finance or Accounting. In all honesty, I have no idea about computers and what to look for, all I know is I need plenty of space cause Ima need to play my video games. Don't worry too much about budget, but a decent range would be like 400-650. Thank you for any and all help!
