Hi guys, I decided that I would like to buy the new 2014 rmbp 15in screen. I definitely want the 15in for the size. My problem is if I should get the one with or without dedicated graphics card? I am a college student and a biology major with a focus on moleculer and cellular biology and genetics. I would use it for... school work reading internet movies/streaming video documents/presentations music the occasional game such as Civ 5 and stuff like it. Not hardcore games So is it worth getting the dedicated graphics card? I would like the computer to last for 4 or more years. Is it worth getting the best one so it will last longer/ will having the the graphics card make the computer last longer? My thinking is since I'm going to spend $2,000 why not spend the extra $300 to get the top of line computer with the thought that it will last longer (is that even true?) Thanks!
