NVidia Quadro FX 4000 SDI

The Quadro series is a line of workstation graphics cards designed to provide the selection of features and processing power required by professional-level graphics processing software. The Quadro FX 3450 and 4000 SDI cards using the PCI-E x16 interface use the same GPU but provide different features. The AGP version of the 4000 SDI provides the same features but lower performance, due to the fact that it uses an older model GPU with a less powerful graphics bus.
