Which of these two Lenovo's is better for schoolwork(Powerpoint, etc.), engineering programs such as AutoCAD, downloading movies, and for gaming. I am not a hardcore gamer, but I want okay gameplay for when I do play. I usually only play Black Ops 2 and lower games, so I would like decent gameplay for that.
