Shaolin -
Ransaak's post is quite accurate. The machine never approaches "unhealthy" temperatures for the notebook, even while gaming. The machine does not even get warm to the touch at any parts of the machine (unless you put your hands near the exhaust vents for some warm air

).
As far as the Prescott CPU, the machine clearly supports it by viewing specs online and by viewing the BIOS revisions. For some reason, they have not added support for the Extreme Edition CPU in the BIOS which they should.
As far as the 1714 model in Europe, I notice on the specs sheet it lists 512KB cache (
