Hi, I'm attempting to build my first computer before I go away to college to become an engineer. I want my computer to be able to run the latest greatest games (Ex. Boarderlands 2, Skyrim, etc.) preferably on 2 screens. But I would also like to know that I will be able to do some light AutoCAD or Inventor work if the need arises. These will be light, mostly single parts or assemblies under 10 components with possibly some simulations. What options are available under ~$200.00?
