Hi guys, how are you? Im from Argentina and I want to buy the SP3 but I dont know which one is better for me. I'm a Civil Engeneering Student and I want to use it at the University to take notes and to work with AutoCAD, Photoshop and Revit programs at the university too. I have a desktop computer to work with the big files at AutoCad o Photoshop and to rendering with Revit. So the SP3 is only for use when I'm not at home. Mi principal question is which one would you recomend me. And I have the questions with the noise fan and heat problems with the I7, because I dont want to have it when Im watching a movie or using Netflix or another soft at mi home. I'm sorry with my English, and thanks for your answers.
