How about this:

Power draw from brick, measured in watts:

Cube, 7457 1400Mhz
VGA and Rage128
peak at HD spinup	              56.00
Nominal, system idle	              44.24
iTunes rip		              52.08

Cube, 7455 1400Mhz
VGA and Rage128
peak at HD spinup	               71.96
Nominal, system idle	               32.76
iTunes rip	  	               84.00

Note than under heavy cpu usage (itunes rip) there is a 52 watt 
increase in power draw over system idle  using the 7455. Only an 8 
watt increase on the 7457.
