Dude, on the fs/ft forum they are selling used 9800pro's for the price of 2 9550's. I'd say go for that type of deal! But remember only pay first on people with long lists of references and be sure to make sure the people that give you a ref site email you from the email. There are lots of tricks to know, read the FAQ if you haven't bought there before.

Thanks for the leads, ncantador. The Zalman stuff looks like overkill. I was hoping to find something passive and cheap; after all, I can get a 9550 card for about $50. I guess I'll just get the new card.
Better than paying another $40 +shipping or so. Only like $12. It wil cool your gpu, it's not just a northbridge cooler. That thing'll cool just about anything that isn't OCed to hell and back when it comes to low end gpu's.
