The second one ofcourse, but why would you get such a shitty video card if you gonna buy the quad 3.0 ghz. Imagine if you could overclock that to atleast 3.4ghz.
I suggest you to get a better video card such as the GTX460.
If your not willing to spend more for a video card. I suggest you to wait and build up some money till christmas and get the second bundle & a good card (GTX 460 )
EDIT: If you are going to buy the bundle @ the HD6670, you wont even be able to run graphicly intense games such as bf3.
