Right now it's like a 1 or 2. There's some machining and prototyping workflows that are really helped because of 3d printers. Areas that can't easily get parts would be greatly helped by 3d printers. Will we ever get to the point where there's a 3d printer in every home? I dunno.
There's just not that many products that 3d printers can produce currently or will produce in the near future that aren't so cheap already it's hard to justify the cost for a common user. Likely if we ever get to the point where I can download the schematic for the latest video card and print it, it'll be using technology and methodologies that are completely different from the way 3d printing is down now.
