Hi, I need some help choosing a laptop for engineering studies in 12th grade and into Uni. I mainly need to run stuff like AutoCad Revit and Inventor. I have been looking at a few computers but I still need some help. I cant deal with a 17 inch screen, its too big for me. It also has to have at least 6 hours of battery life, My budget is around $2700 US. I would appreciate if someone could point me to some laptops I could purchase. Also could someone explain to me if nvidia quadros or consumer cards are better for workstation applications. Thanks.
