Hi guys, I'm on the verge of buying my first macbook pro. Now I decided to go with either the 15" high end or low end, but I can't decide.. List of things I will use it for specifically: -Internet -School stuff -Gaming like (LoL, Dota 2, Star wars old republic coming out in dec.) -Some personal video editing for youtube reviews and some creative videos -Photoshop -Watching videos -And using it almost every single day I know I can upgrade ram and get some ssd hard drives later (does it void the warranty? I hope not..) And I just can't see if I should spend the $400 more... So which would I get? Please help!
