I am planning on buying a new macbook pro this summer and need help customizing it. I never owned a mac before and never customize, i always buy stock. I mainly will be using it for school, engineering programs, and gaming( WoW, BF:BC2, ect.). I tried doing research on SSD's and different ways to up performance. Came to the conclusion of a SSD and high ram. Correct me if im wrong please. I know my way around a computer by replacing parts and such. I know i can get ram for cheaper than what Apple sells it. So i was also wondering if buying it stock then upgrading it with third-party parts is cheaper. Also about the SSD vs a 7200rpm serial ATA drive. Most of the info ive came across deals with Win7, so thought id go here. Thanks for your time.
