Way, way more than you need. For normal (non-game) use, you basically need enough video memory to hold a full-screen image. For a 1920x1080 display, in 24-bit true colour (let's call it 32-bit pixels) that's roughly 8MB. Apart from that you might want the same again for double-buffering, some off-screen work area (especially if you have a second monitor, or a desktop area larger than your actual display), etc.
But I very much doubt if you'll use as much as 32MB of that 256MB. Not that having the extra hurts, of course. I doubt if you can find a graphics subsystem nowadays that has less than 64MB; even notebook computers seem to come with amounts of video memory far in excess of what we used to have in the high-end SGI graphics workstations (I've got 512MB in mine, and nowadays 1GB is common).
