Which video card for editing/converting AVCHD?

Hello. I'm building a new computer for general home use and for editing, converting and watching AVCHD home clips as well as other HD clips. I will most likely use Sony Vegas Movie Studio 9 (not the professional version) for editing. I don't play any games. I need help deciding which video card to get. I've read a lot in this forum and from what I understand, I should get a card that can do the decoding rather than relying on the CPU. Which card should I get though? An nvidia GTX 260 or an ATI HD? If ATI, which one? I'd like to spend under $150.

Here is the system that I'm planning on building. Feel free to provide comments on this as well.

I have 3 cards presently that I've used to record, play and edit OTA HD (Mpeg2) and all have worked fine using Nero Vision. An ATI 2600XT (512MB), GEForce 8600GT (256MB), and ATI 3870 (512MB). As you can see, none are close to high-end (I'm not a gamer so I don't need the top of the line). The only real difference I noted was that the 3870 seemed to speed things up a bit. The files I work with range from 5 to 8 GB each and I often have 3 loaded to make DVDs. Haven't tried Blu-ray, but have no reason to believe any of my present systems can't handle it.

I'm running XP Pro SP3 w/4 GB Ram. CPU's used with the above cards ranged from AMD X2 4200 to 6000.

Bottom line: you don't need to get anywhere near $150.00 unless you need something to play intensive games. If you want to compare cards (use the ones I listed as reference), I suggest Tom's Hardware video card comparison charts. Shows which are better for certain uses (that's why I bought the 3870 - rated better for video than some of the 4XXX series).
