Hey all, I've been reading various threads trying to look for an answer but I haven't been able to pin one down. I am looking to upgrade my 2009 13 inch Macbook pro. I am a hobbiest photographer and use the adobe creative suite a great deal (photoshop/lightroom) to edit my 36mp raw images. I am also a university student so portability is key for me as i have to take my laptop to class every day. I have an external 25 inch monitor that I hook up my laptop to, when I get home to do work. This computer will be my primary device. In terms of the quad and dual core. For my uses, which are quite graphic heavy, would i be at a disadvantage with a 13 inch dual core? Would it be beneficial to upgrade from the i5 to the i7 processor in the 13 inch even though it's still a dual core and not quad? I really find the 15 inch too big for class and thus inconvenient. So I really want to make sure the 13 inch will work for my needs over the next 4 years. I am thinking of getting the 13 inch with: 16 gb ram 1tb hd and maybe the i7 or the i5. Thanks!
