I don't remember exactly, but it's got 32MB of RAM on the video card. Since AutoCad is a vector program instead of a raster imaging tool, it uses a lot less video processing than you'd think, or so I'd been told. I get by with the 400mhz I'm running now. I'm not afraid of that. I just want something that can do AutoCad, play mp3's and is portable for work without having to upgrade again for several years. I think it'll work just fine.
