  1. Recommended video cards for working with IntelliCAD, with decreasing preference:

      

    • NVidia GeForce series
      • 

    • ATI/AMD (working on 4+ monitors is not recommended with ATI/AMD)
      • 

    • NVidia Quadro (it could be worked around)
      • 

    • integrated (Intel/ATI) - usually they have bad performance
      •
