Well i start college next week and my school recommends Mac so im going that way. Ok so i went to best buy the other day and looked at their line up and liked the 15"mbp i like a bigger screen so 15 is fit for my likings. Ok so i was looking at the 2.53GHz which is going for $1,599.00 and the 2.66GHz which is going for 1,849.00. Now is the processor speed noticeable?worth the extra money? and how much better is the graphics card NVIDIA GeForce 9400M + 9600M GT with 256MB over the standard one? My main use for the laptop is mainly going to be for school ( presentations, essays etc) aswell as my traktor pro and logic. Im also a novice photographer as i like to call my self. Also i run midi keyboard and controllers when i want to get creative with my music i dontt know if that matters or not. So my question is, is the 250 worth it? im not a technical guy but it seems to me that i am getting a good value for just an extra 250. SO do you guys have any tips for a noob like me when i go buy it? anything i should be aware of or concernd about? I hear that a new os is coming out friday, will that already come standard in the computer or will it be an extra? thanks, i apprececiate anyone that took time to read and respond to my thread!!!!
