I am going off to college and am required to have a laptop, but will need to run advanced physics simulations and other demanding programs. As such it is asked to purchase a laptop with dedicated graphics, but I do not know where to look. I know I could just buy a gaming laptop like the Asus ROG series or some premium ultrabook, but I don't have the funds to spend $900+ on a laptop. Does anyone have a recommendation for a budget laptop that can handle heavyweight applications? Any advice is appreciated
