A client of mine asked me to build a CAD workstation for them. I am looking at either the Nvidia Quadro FX 4600 ~$1500 or the AMD/ATI FireGL v7700 ~$1000. To the best of my knowledge they will be using AutoCAD (not sure which version, 2007 or 2008) and CADDuct. I can't find a workstation video card comparison chart that has these 2 cards in it so I was seeking the input of you guys in here. thanks.
