Maybe she can swap a video card with you or someone else that is a different brand but of equal value? That way she won't have to buy a new card.
Usually I find cheap video cards from:

I'm a fan of the generic Riva TNT2 AGP card, usually bought for under $30 with 16M of RAM or more. GeForce 2 or 4 generic card for $45 isn't that bad either.
Nightowl, check out PCOnramp.com, they are EPC and they are local. If the card doesn't work they can take it back and trade you for a different one. They have more in their store than is shown on the web page, but they have directions to get there if you don't mind driving out to St. Charles.
