Hello, I am buying a new imac here pretty soon. The specs for the one i am getting are: 1gig ram 250gig HD 2ghz processor wireless mouse and keyboard ATI Radeon 9600 with 128MB DDR Video Memory I am going to be editing movies and creating music for them and just for fun, ya know. Would it be wise to get 2 gigs of ram? or can i buy another stick cheaper and just put it in there? and also, is the performance of the bluetooth mouse and keyboard worth the money? thanks, lake denman.
