And as far as contribution, isn't 1 hr of electricty on a 500mhz box like 1 hr of electricty on a 1ghz box?
There are some difference amongst different processors concerning power usage. Here is a article/chart that details some examples.
From the article: "This is not the result of us choosing processors to bias the test. The Intel 630, just about the slowest desktop P4 Intel offers at this time, draws more power than the AMD A64 X2 4800+, the second most powerful desktop processor AMD offers currently. To top it off, the 630 is a single core processor while the X2 4800+ is a dual core." I reason from this example that this P4 is going to spend more time using more power to crunch a wu than the 4800+ would for the same wu.

The guy that spends 60 minutes crunching on his 500mhz Pent on WU's gets the same "credit" as 60 minutes on a Pent 4 at 2gig crunching WU's..
They both contributed 1h of time... While othere won't agree, this is a valid measure that can be used for any project on any HW/SW, and will level the playing field...
True, they both would've contributed an hour of computing time. But from a project standpoint, the faster box is more productive. To use an analogy, consider two workers at the same place of employment. Worker "A" is responsible for stocking, picking, and filling orders. He is also responsible for customer relations including ordering, plus taking care of inventory and placing orders to various suppliers. Worker "B" is a temporary hire that's been brought in for general clean up. They both worked an 8 hour day. Should they both be paid the $7/hr. normal temp. pay or $12/hr. warehouseman's pay? Sorry if the analogy is weak but I think it illustrates my point.
