i just got a dual-core 2.0, up from a 1.67 G4. I have to say i'm really dissapointed. This computer isn't fast at all, its about the same speed as the powerbook. and the mighty mouse just sucks. I think i might sell it. does it get better with time? Plust it makes some wierd noises, which haven't notice on other g5's i use at school?
