The short answer… No You will be just fine with a 128mb graphics card or even a 64mb card for video editing. I have a pretty decent 256mb nvidia card that really wasn’t too expensive, but the reason I got it was for the dual monitor ports. Shop around and get a nice card that will do what you want it to, but you don’t need to spend tons of money on it for video editing. Gaming, like you said is where the monster video cards come into play.
