Yeah umm if he is using CAD, Will definatley need a Gfx card, I have ACAD 2007 and I have a ATI 256 MB card in there, which is either minimum or recommended, and I have a 3GHz proc with 1GB RAM and running the 3D models, well it chugs and is kind of choppy at times, I even try to disable as many non essential startup/services items as well. The most important thing CAD needs is a vid card So add that into your price tag, I have been told to buy a 512MB vid card, but They ain't that cheap here....
