I am planning on purchasing a new laptop. Now that I'm in grad school for engineering, I need something with very high processing speeds and good graphics. The programs I plan to run are: ProE, Fluent, NASTRAN/PATRAN (finite element), a Robotics simulation program, CAD, Inventor 11, MATLAB, and Mathematica. What is the best laptop for engineers, in your opinion? Any help/input is greatly appreciated!
