Question : Which Type of Graphic Card

I placed an order for my graphic card but it turns out they don't stock it anymore:( I need an advice on which type of card that is suitable for my old PC. I would spend about £40/$55. I do get confused with DDR and DDR2 and whether i can get a 128bit memory interface as the dell maual suggest maximum connector data width (maximum): 32 bits. I'm probably confusing myself here.

Answer : Which Type of Graphic Card

you can buy any kind of AGP (8x or 4X or even 2x) video card. You currently have 128M Video RAM, you can get the same or more (256M, or 512M) if they are within your budget.
