I play games on Linux. Some of my favorites are D2X-XL, Nethack, and Rocks'n'Diamonds.
My 17" laptop uses 15w at idle (down to about 10w or less with the screen off), 20w in typical use, and it maxes out at about 50w with a heavy load. Not bad considering it has a 1.6GHz Core 2 Duo and a 8600m GT.
Recently, Gentoo got support for offloading video decoding to Hannah Montana (the DSP onboard Nvidia 8 and above video cards, including the 8600m GT in my laptop), but I have to actually measure the power usage to determine if it is more efficient than using the CPU. It is really made for improving system performance when multitasking while viewing videos.
