Please help. I am planning on a buying a new iMac when they are updated, but I am trying to figure out what to to with my old G4DP450. Right now, I have a 32mg video card, but I can upgrade to the ATI9200 for $129. My question: is it worth it to upgrade the video card (mostly to run Tiger - I've already pre-ordered)? Or will I also need to upgrade the processor? I have no personal experience with upgraded mother boards, and I certainly don't want to spend a lot of money on an older machine. Even if the kids are going to use the old one most of the time, I plan on have the latest operating system on both. Many thanks, Blair P.S. Saw FCP5 demos at NAB. WOW! Really cool. I know this is off topic, but it is a P.S.
