Graphics card power savings

[gwyddn]

My current config is a Nforce 650i mobo and 9800GT graphics card. I don't game often so I hate powering that hungry graphics card all the time (my rig is on 24/7). What's the best upgrade path that will allow me to occasionally game (fallout 3) while saving power the rest of the time? I'm considering the Core i5 for my next upgrade.

thx,
J

Underclocking.

What about Hybrid graphics? Or do newer video cards have power saving features that'd mean my uber-powerful card was auto-underclocked when I wasn't gaming?
