Almost any SE video card is going to be crap.
Just look at the specs. Most SE video cards have a gimped memory bus size and will perform much like a previous-gen card, if not worse. I've seen a few LE cards that looked promising, but i would still suggest against it.
For that generation of cards, I suggest something ATi, in the 96-9800 range. Anything else won't be able to keep up.
