[quote=@Raxacoricofallapatorius]The graphics card isn't as urgent because there's a built-in one already.[/quote]

Built-in graphics chips are really only meant to display basic visual elements, like the operating system itself and YouTube videos. Anything more strenuous than that and they give up. So, if you're interest in creating a computer suitable for playing videogames on, I'd definitely get the graphics card sorted ASAP.
