The system requirements for AutoCAD 2013 are pretty much the same as the last two releases with the exception of no longer officially supporting Windows Vista (not blocked on install just not supported.) Remember system requirements are not a one size fits all as there are a number of factors that affect how much resources your system may require. The factors can be from the complexity of your drawings, 2D or 3D, visual styles. These requirements are also the lowest suggested system optimal requirements, so use it as a suggested baseline.
