Do you have an Nvidia card in the computer? Nvidia has been notorious for promising cutting edge cards even as their foundary partners are unable to produce the chips in quantity.
I’d change the order to an ATI 5800 or 5900-series card, if so.
Yes on the Nvidia card.
The thing is, why can’t Dell simply tell me that is the problem. Yes having the delay is frustrating but their lack of communication is awful and just plain shameful for an American company.
