I am an illustration student and WoW player and wondering which notebook to buy. I dont really have a budget but i've been really confused about DDR2 vs. DDR3 memory in the current selection of notebooks. At the moment im looking at either buying a Macbook pro with 2GB DDR3 or Macbook with 4GB DDR2. The difference between these two is roughly £60 abut im not sure if i should spend the extra cash on the macbook pro? I have a 2 year old imac with 2GB DDR2 and this runs all my programs quickly and without much trouble. I mainly run Photoshop CS3, Illustrator, World of Warcraft and the usual internet apps. My last powerbook G4 was unable to run World of Warcraft efficiently after 2 years or so and i dont really want the same happening with my next notebook. So if anyone can help me choose, it would be awesome! thanks.
