Without having used a watt-hour meter to determine it, I suspect also that a 9600 is streets ahead of the rest of my flock. My 9600/400MHz/45GB (in four drives), with four PCI cards active, an Agfa e50 USB scanner, a LaCie FireWire CD-R/RW burner, and an attached (even if it is only pass-through mains power) 17" CRT Studio Display, must win hands-down. No wonder that the 9600 is heavy, given that sort of a diet, nor that the 512Ke is so slight on its miserable 60-W allowance.

When I get the Quadra 950 going properly, it may not be far behind the 9600.
