You are certainly better off with a gig-- I got two for my second puter because we never know what the future may hold, But I have my doubts that the system can access all of it. I do know on XP when I raised my ram from 385 to 1 gig, you would have thought I got a shot of adrenalin. iT made a real tangible difference. I was losing renders because the textures were too much, even 3000 by 3000 which isn't unreasonable wouldn't render when I'd added some quality props. 4000 by 4000 wouldn't render at all. So, yeah, if you can afford it, get the gig. Emily
