I have a lower end macbook and an 17" iMac and i use both. i'm switching my major to computer science and im 21, i'm going to buy the nintendo wii to game on. is there any reason to try to sell the imac on ebay and try to make what i paid for it? (overseas etc.) to get a core duo 2 imac? i understand the core duo 2 imac performs 50% "better"? i thought the computer was fast to begin with, the thought jumped in my head for one second basically to just "have the latest and it would last me longer" but i really dont know, so i am asking for some advice from some smart people.
