The video card has nothing to do with video editing. Depending on the editing software you use, it can be handy to have a second output that's for analog TV so you can view the video on the target output device. I have a cheapy Radeon 9000 128 meger with that.
But in general, a $30 video card with 32 meg ram is about as useful as a top of the line $400 gamers dream for video work.
