Gaming setup

PC gaming has always been my passion and it really helps me to reduce my stress levels when I get back home from school. I've met one of my greatest friends over the internet, but since the games are getting better and better these days, it requires a lot of specifications to run them. I don't have a great computer nor can afford one.. so I really hope you could help me out so I can build one. Even a euro or a dollar could help me reach my goal!
I really hope that with the money I could buy a new computer and inspire a lot of people by making creative content on Youtube and twitch.tv! I hope you took the time to read this message. Have a nice day!
