The NVIDIA Quadro FX 3500M was the top professional graphic solution for the mobile use in 2007. The Quadro FX 3500M is especially suitable for CAD, digital image-, video editing and scientifical visualizations (according NVIDIA). It is based upon the NVIDIA GeForce Go 7950GTX. Therefore also a good gaming performance can be expected (for 2007 and if modded drivers are used). The card is shipped with certified drivers for professional applications, which are not optimized for games (inofficially the manual installation of Forceware drivers should be possible).
The drivers of the Quadro FX series are certified for CAD applications (e.g. AutoCad, Inventor, Solidstation, Solud Edge, ...) and DCC applictions (e.g. Maya, 3DS Max, Lightwave 3D, ...) and offers a 12-Bit precision for Subpixel, full image Antialiasing, hardware accelerated Antialiasing for dots and lines and additional optimized settings, which are optimized for CAD and DCC.
Nvidia describes the 3000 series as a power package for big laptops and data structures.
