Hello, I just recently sold my 13" Macbook and upgraded to a 15" MBP. Im by no means a power user...my main reason for doing this was for the dedicated graphics card, and because i feel like the 15" will retain its value better because its a "pro". My 13" handled everything just fine, except for the Diablo 3 beta, but im pretty sure the 15" will be able to handle it just fine.(probably on low settings, but idc...i just want to be able to play it) Sold: $700 13" 2008 Aluminum Macbook 2.4 Ghz C2D 4GB ram Nvidia 9400m Bought: $800 15" 2009 MBP 2.8 Ghz C2D 4 GB ram Nvidia 9400M + 9600M So what do you think guys? Good upgrade for $100?
