The latest nVidia drivers (version 71.84) are shown to be certified for use with SolidWorks; however, I've encountered a problem while using them with a Quadro FX3400 graphics card. For example, on certain features (especially Base solids) the cursor selection of a single face results in the highlighting of multiple faces (sometimes even ones on the far side of the object displayed in shaded mode). Then, as the higlighted part is rotated, the extraneous highlights tend to disappear and reappear. Having the extra faces highlighted makes it awkward to be sure of which face (or series of faces) was purposely selected, especially when working quickly during view rotations. Just a heads up...
