The system requirements for AutoCAD2012 are pretty much the same as the last release. If you are using AutoCAD 2011 or AutoCAD 2010 just fine, you should be good to go with AutoCAD 2012. Remember system requirements are not a one size fits all as there are a number of factors that affect how much resources you require. The factors can be from the complexity of your drawings, 2D or 3D, visual styles such as a 3D part as wireframe takes less than one with a smooth shaded view, and certainly the size of your drawings. These requirements are also the lowest suggested system optimal requirements, so use it as a suggested baseline.
