I'm looking to purchase a the 15" MBP. Besides the typical surfing and emailing, the most intensive application that will be run is WoW (World of Warcraft). Other than that...no other gaming will be done. The main debate due to the last requirement is: 1) Do I go for the version w/ just the GeForce 9400? 2) or the 9400 + GeForce 9600M GT? The main arguments are: 1) MBP's with the 9600's have Overheating issues during intensive apps. 2) Will just the 9400 suffice for WoW? (The family is currently playing WoW on a 5 year old Dell Inspiron 9200...I'm pretty positive anything newer than that will play smoother) Any opinions/suggestions?
