Energy Effecient GPU for HTPC?

[WintersFury]

Ok, so I'm perhaps looking for a new video card for my HTPC. I currently use a x1600Pro in it which I'm not sure how much energy it uses. I have the computer on 24/7 so I try and make it as energy effecient as possible.

I'm looking for something that uses little energy when idle or 2d dvd / video playback usage. For all I know my current card may be comparable to the newer cards in that respect and I'm hoping that's the case.

So how is the x1600Pro energy usage wise, and if it's not that good what could be a good card to get in it's place?

Thanks!

HD3450 series. These are cheap enough that I wouldn't consider anything else in this price
bracket for HTPC use.
