Sample D3 and D800 images at 6400 ISO resized to the same size

Coming from someone who has a D300s and can't shoot much over ISO 800 without terrible noise, I find this thread (and the other thousand like it) silly.  All this downsizing, etc - just tell us which camera RAW files out of the box are the best.  If D800 is better but needs 30 minutes of PP for each shot then no thanks.  Honestly both are incredible to me - you should all stop experimenting and go out and take some pictures.
