I am going to be buying a new laptop computer in the next few weeks. Im leaning toward getting a MacBook Pro, I dont think I need a 17" screen so most likely I will be getting one of the two 15.4" inch models. The problem is that I dont know which of the two models is the best buy. It looks to me like the only MAJOR difference is a 2.4 processor with 3MB L2 on the base pro or a 2.5 processor with a 6MB L2 on the mid range. The only other real difference is the graphics card at 256MB or 512MB. Basically, i dont understand if those two things are worth the $500 price bump. I am a college student so money is an issue so if they will not help the overall performance of my system significantly I will probably go with the base MBP. Any advice would be greatly appreciated. Also, is it worth it performace wise to spend the extra $100 or so to upgrade a hard drive from 5400 to 7200 rpm. Thanks for any help!!!
