going to sell my 4-year-old dell 933 xps to a friend who just needs a cheap computer, but the GeForce2 GTS Pro 4x AGP 64Mb card died a month ago. whats the cheapest card i can put in a 4x agp slot so i can sell this comp? he's only going to be using it for basic tasks, but the mobo has no on-board video, so i'm stuck getting a new card.
