Additional Comments: So my beloved laptop has just died and I thought to my self what better time than to build my own PC. I will be using it for basic editing of videos and pictures with programs such as PhotoShop, cinema 4D and Sony Vegas Pro. I will also want to run Minecraft and a screen recorder (Either Fraps, Bandicam or Camtasia) The only problem is I have never built a PC before and I am on a budget of around $600. If you could give me some ideas on what I need and don't need as well as where I can get it from it would be much appreciated, I would also like to know some recommendations on parts and what will and won't work with each other. Needs to be fast and able to run without too much lag. Must be able to run Minecraft on full settings no lag with the screen recorder on and to be able to edit quickly.

Thanks in advance,

P.S: I live in Melbourne, Australia but I can use online stores.
