Precisions are business/professional workstations, the graphic cards like the quadro are isv certified for a long list of apps. their standard warantees are 3 years also.

If you spend 30-100% of your time doing CAD on that machine, you need to get a certified card like the Quadro. It has a very very different set of drivers and the hardware is tuned toward design/engineering apps.

The Dimension is the basic home computing line. Yes, the GeForce cards are screamers and great for gaming. The Quadro FX1400 fares just fine for that also but excels in other areas. We have both and our systems are PWS 380's and 670's.
We did have several Dimensions too and a XPS600 though not for work.

You might want to look at this thread from tom's hardware regarding consumer/professional graphic card issues:

This is only my opinion. It all depends on your business and personal needs, the applications you consider to be mission critical, and such. I prefer to have the best hardware suited to my profession and the way I work on a daily basis.

Thanks for the reply! I know that the "Precision" line is Dell's
business/professional line, but I haven't been (still am not entirely)
clear on what that really MEANS, if you see what I mean.

Gaming boxes (e.g. the XPS) are generally fast & have lots of memory;
that strikes me as much the same criteria as a CAD workstation. So it
comes down to looking at some finer-grained details (bus speeds; the
stability of the chipset; ECC vs. non-ECC RAM... and, of course, the
video card).

Concerning the video card... I had seen, e.g., the nVidia whitepaper:
www.pny.com/support/downloads/quadro_geforce.pdf
Thing is, it seemed heavy on qualitative claims, and light on actual
comparative numbers; in short, a marketing whitepaper. I don't often
trust marketing at face value... call me cynical.

The thread from Toms Hardware was good data for me; thanks! It looks
like the hardcore engineers will really appreciate the Quadro features;
i.e. it's not just marketspeak.


Thanks again!
