Thanks for the ATI caution.
$1,200 does seem to be too short for the budget.
The most affordable GFX card for the work in that price range is the QUADRO 540, which I can't find reviews for, so I dunno how it would handle with a Pentium D 930.
We're looking to up the budget to at least go for a QUADRO in the 1000 series range.
What about monitors:
Would LCDs (in the $300 price range) be okay for CAD work or is the performance of CRT a must?
