Agreed. I would love to see an really comprehensive review of the thermal pastes available today. If you do do this, make sure to use several heatsinks; an enthusiast one and a stock one. This will allow mild overclockers to see the advantage of decent thermal paste, even with the stock heatsink.
And please, use both an Intel and an AMD
You could also include a guide of heatsink lapping and IHS removal if you were so inclined.
