The Matrox G450 is a follow up to the Matrox G400, in fact it is really just a tweaked version of the G400. What makes this card special is its support for two monitors, and really high resolutions. This card can display 32bit color at 2048 x 1536 @ 85Hz. I do not know of many monitors that can display resolutions as high as 2048x1536, and I don´t know of any that can do it at 85Hz. Don´t expect to hit that resolution on two monitors, the second monitor can only display 1600x1200. This is because the card has two independent RAMDAC´s the primary runs at 360MHz while the secondary only runs at 230MHz. While using two monitors the most you can do is 1600x1200 on each monitor.
