There are also some enviromental issues, you shouldnt just waste electric energy like that. Using that kind of argumentation, we should all be using power inefficient consumer electronics  |
As I said before, I do know my bills a lot better than you =) And I pay exactly the same price for electrical heating as I do for electrical computing. In fact, my power company can`t tell if the current is flowing through a heating element or a processor =)
I am aware that most countries have more problems with cooling thier houses properly than heating it, but Norway is cold most of the yeahr, and we have plenty of waterfalls ;-) Most appartements have no other source of heat than electricity.

From a noise perspective regarding the CPU the only parameter is the CPU thermal dissipation, if its hot it requires more cooling, which tends to be noiser. If you can cool a P4 silently ( passively? ), then fine, but in that sense any CPU can be cooled silently, and then there is no need to prefer one over the other for noise reasons at *all*. You can always take any cooling solution for a hot CPU and apply it to a cool CPU with the same or less noise resulting.
I could see your point if choosing the energy efficient solution had some disadvantage, but i dont see any. Currently the AMD / Core Duo systems are just plain better than their Pentium D counterparts both when seen from a performance-per-watt, performance-per-price, and performance overall point of view.

When I bought my systems, I bought the options that made most sense at that time. I am not argueing that p4 precotts are simple to cool silently. In fact, I cant remember exactly what I was argueing ;-) I think it had something to do with your bold, "eith-or" statements, when reality is always complex and faceted.
It used to be at least, that no processor could beat the p4 at running ffdshow really, really fast.
