Every now and then you'll see Tom's hardware do pretty much exactly what your asking.
The main issue with doing what your asking is time and hardware availability.

A lot of reviewers actually pay for the hardware, so yeah they may end up getting samples of the GTX780 to review but they still have to cough up for the rest of the rig, so imagine having to do that.
They also have strict dead lines.
