I am looking at both low end and high end 15" models, and can't decide in which one I need! I wanna go with the high end model but its $300 more then the low end with the student discount. I will be using mostly use producing and mixing programs on it, for an example pro tools fruity loops. But I will also web browse, listen to music, edit some HD video on imovie, and do some word processing. Is the AMD Radeon HD 6490M on the low end good enough for pro tools and Logic Studio? If i do any gaming it will probably be the sims. Any help is appreciated thanks!
