You should have gotten a score between 3000 and 4000. I would definately call for some customer service. Have you checked to see if the fan was working, or if the heatsink set up looked like it might not be attached right? Check the cards temp to see if its normal or high.
Edit: also I just realized that you're talking about an AGP card. That card requires more power than can be provided by the AGP slot, so make sure that you have the proper lead from the power supply plugged into the card.
