4670 because it'll have driver support for longer, and because I'm decently sure it runs cooler.
That 256-bit bus won't be necessary on a lower-end card such as that 4670 anyhow.
Edit: And it uses less power, so you don't have to shell out on a power supply (especially if you want CF options in the future).
