In My computer I have an agp 4x but don't know what graphic cards will fit or even where to start looking. The dell rep said I need something like an AtiRage ultra128, 32MB full height or ati Radeon7500 w/tv out 32MB full height. At Christmas was given an ATIRadeon hd 3650 8x with 1 gig ddr2 memory. It will not work. I priced it at best buy and it was $149.95. It is still brand new and in the box. Will be willing to trade for a graphic card that will fit my dell 260 4x agp slot. Please tell me what a pci 2.2 slot if for. The dell tech said he really didn't know.
