I need a new mac! My G4/400 is getting old. Its a Yikes! too. It has 384mb of Ram, V5 5500, a 13gb HD and a 40gb. With DVD. If I get a new comp I'll take my 40gb out and place it it my new comp. How much money could I get for this comp? Second question, what Mac should I get? If i get the 933 or DualGig should I drop the 4MX for the 7500, or even GeForce Ti?
