Hey guys... I'm the proud owner of a TiBook 550 MHz with combo drive. I'm thinking of replacing it with either a 12" PowerBook or a 900 MHz iBook. My question is this: Which of the two graphic processors is better: The NVIDIA GeForce 4 420 Go processor, or the ATI Mobility Radeon 7500? They both have 32 MB of DDR SDRAM. The reason I'm not automatically opting for the PowerBook is that I also have a new iMac, so if I have any processor-intensive tasks, I can do it on the iMac. PowerBook is $1799 and iBook is $1299. Any thoughts? Chris Owens Cincinnati, Ohio (513) 861-3104 home (513) 807-3104 mobile office ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Friendship: A soul dwelling in two bodies." ~Aristotle~
