What's the power usage of those things? I think I'd notice the difference in my power bill vs buying something like an i5.

- walrus01 10y agoA xeon e5 2665 is rated at 115W thermal, so two of them at full load (let's say, calculating prime numbers) would be 230W... plus the overhead for fans, motherboard, hard drive other heat producing components in the system. I would guess that the lenovo workstation in the ebay link is probably 310W electrical load as measured by a kill-a-watt if you run simultaneous full cpu, ram and disk benchmarks on it. Depends a lot on your electrical cost. Some people live in places where the power costs $0.05 per kWh. Some people live in places where it cost $0.36 per kWh (Hawaii).
