Here is a good starter gaming computer that I made on PC Part Picker and it may not be a great computer but it is a good starter computer and will get you the FPS you need for most games. The graphics card installed is an integrated one and is not the best, but it'll get you not too bad fps, also it is a $300 build and you will have to do it yourself, it doesn't include an optical drive or an OS, so you can install it off a download on a flash drive or get an optical drive.
