Hello Experts - I am looking for recommendations for a high end CAD and rendering workstation. I work for an architectural firm and on occasion we have need for a very fast machine to render CAD drawings, create walk-through animations, and convert large amounts of data to PDF files. I'd like to buy a really high end machine that my users can share when they need to run a very resource intensive operation. In the past I've used Dell Precision workstations and while they are fine I'm hoping to find machines designed specifically for the tasks I mentioned above. Please let me know what you think, thanks!
