These aren't really dual core CPU's they are single core with hyper-
threading. If you disable hyper-threading you'll get more performance.
You'll never get that great of performance out of these CPU's. The
new 64bit woodcrest/clovertown Xeon's are much better... night and day
difference. (Pinto vs Porsche)
