my wife be unable to watch espn3 's live streaming video on she Dell 2400 with on board video and a 22 inch monitor . I replace the motherboard with a Dell 4600 motherboard which have a 8x agp slot . the card install easily and perform well at the recommend monitor resolution 1680 x 1050 . the difference in the quality of the video be incredible . it perform well for the purpose of watch live streaming video . we do not do any gaming so this card suit we need perfectly . I be use a Dell 250 watt power supply with 14 amp on the 12 volt rail with no problem . the card run cool and quite with the on board heat sink . I also test this card with a older computer with a 4x agp slot and work well in that computer as well . I can highly recommend this card for any one who want to upgrade they on board video in a older computer . it be a great card for the money .
