Actually, yes, you should upgrade you computer... to a Mac dual G5. (/me ducks and runzlakhell, laughing maniacally...) Okay, in honesty - the dual Xeon should run it well enough. Otherwise, it'll be hard to tell if P6 will be "worth it", since nobody outside of CL and their cadre of beta testers know what it can and cannot do yet. I'm personally holding out until I hear from other Mac users (post-release) on any increases in efficiency and speed before I bother. /P
