Hi all. I have to deal with large to huge DTM dwg's. Our MIS dept. seems to think an entry-level cpu and graphics card are good enough (1.6ghz pIII/3dforce2 64mb). I do have 768 MB RAM. Am I off base in thinking that a higher end system is going to make a big difference? Does the graphics card need to have its' own OpenGL driver written for AutoCAD? Thanks. donn
