Where to compare dof between the 6D and 1D4?

Since the 6D uses a FF sensor, it should allow for less dof than my 1D4 (1.3 sensor).

Is there a site that compares images from these two cameras? For example, if both cameras had a 24mm lens @ f2.8, I'd like to see how much less dof the 6D provides.

I bought my 1D4 for air shows, for the fast and accurate AF. But I like to shoot car shows (static displays) and museums, and for that it seems the 6D will give me these advantages...

Less dof for blurred back grounds

Wider fov when used with the 24-70 f2.8 II

Better at lifting shadows and recovering highlights (at least I think it might be)

Smaller and lighter body.
