I have a Matrox RTX100 and and I can't complain about it.. But, as he said, for video editing nowadays you don't need necessarily a card like that.
Your decision is depending what kind of raw video you are thinking to edit.. If this video comes from analog sources, go to a card. But if it is only from DV equipments, you can only adquire a Firewire cheap-card.
The great advantage of Matrox and other cards that makes effects realtime is that you don't need to wait while you playing the video: There's a micro-processor inside these cards that helps CPU to run without pre-processing. It's very important for some intense-consuming effects, like chroma-keying, twirls, 3D...
I can assure to you that if you want speed and if you like to edit video, you'll love RTX100 - and so, at the finishing you'll encode the edited video in realtime speed: MPEG2, WMV, MPG and DV AVI.
