Cheapest 1400x900 resolution card

I've got a friend with an old computer not worthy of a decent video card. He did just get a 1400x900 wide screen LCD. Of course his existing video card won't run that resolution and all the non-native resolutions look like crap. So I've been looking around for a cheap card and can't find any documentation on what resolutions are supported. Perhaps all the new cards do, but I'm looking in the $30 range, which tends to mean new cards need not apply. I would really like to avoid buying a card only to find out it doesn't support the needed resolution.

This 5 year old Dell has an AGP slot of indeterminate speed and PCI slots available. Suggestions? Links?

That's what I thought, until my collection of five year old video cards all bombed out, now I'm a little gun shy. I found out it has an AGP 4x slot (will all AGP 8x cards work?). One other tip, this machine isn't used for gaming, just IE and Office.

For example: damn, link didn't work. Follow http://www.tigerdirect.com

I'm looking at the three $29.99 cards.

Diablotek Radeon 9550 64MB AGP8x
Diablotek Radeon 7500 128MB AGP 4x
GeCube Radeon 7000 64MB AGP 8x

Anyone have a preference?

If you think something is fishy I'll stay away, that's why I asked. Here are the links to the 3 cards in question. Maybe you will spot where the discrepency is:

Based on the recommendation I'll go with this one unless someone else tells me $10 more will get a much better card:

Even in Vista you shouldn't really need large amounts of video memory because with any of those cards you won't be running the high end interface. Even if you were, the speed of the card would be more of a hinderance than the amount of texture memory. That being said, the 9550 should easily be the fastest in that bunch, and it certainly supports more advanced features. Its a DX9 capable whereas the 7x00 series is not. I'm not sure what Vista requires as its minimum, but a 7x00 seems iffy.
