Hi again desigirl .According to the Dell manual your small mini tower agp slot is 4x & 1.5 volts .so you need a card that is 4x rated ,a 4x/8x would proberly be fine ,but an 8x card might not work on that voltage , I would be tempted to pop into your local pc shop and ask there opinion , also having looked around it looks like it needs to be a low profile card .Dude044
Anyone else in here want to have a say ?
