What you need for this book

In order to install and use the Microsoft XNA 4.0 tools, you will need a Windows PC with either Microsoft Windows Vista or Microsoft Windows 7, and a video card supporting DirectX 9 or later. Shader Model 1.1 is required for XNA, but it is highly recommended that your video card support Shader Model 2.0 or later, as many of the XNA samples available online require 2.0 support.
