If I did that with the aforementioned Dell 490, I could get *TWO* of the Quad Core Intel® Xeon® Processor E5320 1.86GHz,2X4M L2,1066(ESMT) CPU chips and the price out the door would be under $2,600 (for the $4,100 system above). If I had $5,000 (or more) to spend on BOINC contributions, I could buy multiple copies of that $2,600 machine (with a KVM switch, of course) and I bet that my total BOINC contribution (credits) would be a lot better than the person buying the Mac Pro with dual 3 GHz CPU chips.

Skip the KVM and just use VNC. Less HW to buy and cable up. It's already on the network anyway.

Yes, you will probably out crunch a single top-end 8-way with 2x low-end 8-ways. But you will also have 2x the power consumption to pay for, two times the heat exhaust to deal with, two times, the noise, and two times the footprint/space consumption.

Exactly. In case anyone wonder about the comparatively low RAC for my Mac mini http://einsteinathome.org/host/932558: Only one core is working for E@H, the other one is here on CPDN: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/show_host_detail.php?hostid=649055.

Watts are per second by

Watts are per second by definition. A Watt is a Joule/second. And a Joule is the energy needed to heat 1g of liquid water 1 degree Celcius. Bikeman converted it to the kwh's that your electricity is billed in. Joule*hours/second, a truely bastardized unit if I ever saw one.

If you are used to metric units e.g. "Liters of gasoline per 100 km", "miles per gallon" is quite painful as well :-)

Inverse units are a pain for thinking in, but there's nothing fundamentally wrong with either formulation. My comment was about the fundamental perversity of the unit kwh from a strictly dimensional PoV.

Eh, that was such a massive mind-bending revelation! I think the gravity of it hit me at 299792458 m/s... no, wait, that was 9.8 something or another... :shrug:

Perhaps I should be made to walk off the plank for not remembering that I am carring around a cup of tea that I am swirling at the rate of 6.626068 × 10-34 m2 kg / s

What is the best operating

What is the best operating system (?way) to get the maximum BOINCing from a DL-580 4 Xeon Piii 700MHz 2GB?

You are not alone ... you might want to add your experiences to this thread here .

I'd begin with a Live-CD Linux version to check out the system and get a first impression of the performance. I doubt you will get better performance under Windows.

Perhaps the real question

Perhaps the real question should be "how many cores" is better. I'd say the more the better. For BOINC, parallelism is a great thing. 2 cores let you do two tasks at the same time; 4 cores - 4 tasks, 8 cores... you get the picture. Plus, the more cores per case means less occupied space.

And if you have a small room or apartment, a many core computer can serve as a space heater. If you live in a warm place you may want to avoid getting too many cores.
