ok i currently have a 8 year old emac 1 ghz so i feel its time to upgrade The new macbook pros look amazing and are exactly what i want but i am having trouble deciding on which model is right for me. I feel the 13' are beautiful machines but the nvidea 1400M seems kinda week especialy for the casual gaming i do this also removes the lower end macbook pro 15" I also believe the 17" is too large for my needs. So i have two models to choose from The 15" with 2.66 ghz and nvidea 9600M GT with 256MB or the 15" with 2.8 ghz and nvidea 9600M GT with 512MB i would want them both to have a 500 gb hard drive and i am perfectly fine with 4gb of ram. Which model should i choose? Is it worth upgrading hard drive to 7200 rpm? If i start playing more graphicaly intense games would the 512 MB one be way more effective? Im going off to university next year do i qualify for student discount now? If i purchase it now will i get SL free or will i have to pay 29$ for it?
