GuitarDave I replied earlier but got deleted; I guess due to the
title change.
Anyways, the gist was; I have found that with Dell sometimes the spec changes perhaps due to stock levels, offers, component shortage, etc., don't know exactly the reason but it seem like if you see it buy it or loose it.
About the graphics card, a 1GB separate card is better I think than a 1GB integrated and is still a good spec. I guess it depends on what you need it for, games, 3D CAD, design, annimation. I have seen the 3GB cards you refer to also capable of 3D but requiring a better quality screen. I've not seen it in the Inspiron range but in the XPS range for sure. However I thought the price was closer to the 1K and above bracket for that configuration. I was looking only recently to nab one for myself.
