I need a build for gaming that is under $800 dollars. The catch is, I still need a monitor and such. I can get the OS for free so I just need a keyboard and mouse lets say $50 for that and $100 for a monitor. So really I need a $600 dollar gaming computer made up. Can someone create me a build that I can start messing around with? It would be much appreciated. Just trying to get some ideas flowing since it's my first build.
