PC build with AutoCAD in mind (Low Budget)

[Luke2]

Hello, firstly I'd like to say that this forum has helped me gather much knowledge about building PC's and get my own PC build up and running with no issues. So thanks all of You for that. Now to my question.

I had a very good friend of mine ask me to put together a system which will be used for working with CAD software.

I do not have any experience with building CAD workstations, do I go for the Quadro videocard ? Is there any particular parts that I should be looking for instead of the regular cookie-cutter gaming builds ?
I would imagine computers like these need to be stable and somewhat powerful, however no gaming will be performed on this, so that poses me to ask the Pros here.

The budget.... Well, he told me "somewhere" in the range of $500, however I believe the flexibility is there, so if there is something that would be really worth getting in terms of performance, then I'm sure he would be willing to go to $700. Somewhere within that range.

Monitors/OS/Peripherals need NOT to be included in this. I am mainly looking for advice in choosing the core components such as MOBO/CPU/VC/PSU. All else I could possibly pick out myself. One last note, He will be running dual screens.

Thanks for Your time.
Luke

Just under 700 bucks with an operating system - add keyboard, mouse, and montors.

Glc, thank you so much for your fast lightning reply.
Since the Operating System will not be needed and he would like to run a dual monitor setup, I was thinking possibly I could switch the video card to something like this ?
