If it were clear how much two and four cores benefit over a single, it would help many make much more informed decisions.Does this website have the resources to aquire the HW and test a C2D with one core disabled, running two cores, and a quad, all at the same speed?Certainly somebody could make it happen, and it would be a great service to the community.

A site like HardOCP might do this... maybe I'll email em and ask.
