My girlfriend currently uses a G4 700Mhz Power Mac but is finding she has to do 12 hour renders. She upgraded to 2gb RAM when she bought it new and got a new Radeon card very recently but the machine seems to be grinding to a halt. My question is what machine should she upgrade to ? She has to visit clients and making video work onsite would be an advantage. There's a limited budget available but I have been trying to persuade her that a new 15" powerbook would be ideal (superdrive and s-video out very desirable to her) Is a powerbook powerful enough to use after effects with? Is she better off buying a G5 powermac and not bothering with a portable? Any advice gratefully received !
