Looks pretty damn linear to me.
The image i copied is from another test coolaler ran with a "regular" e6700

Well, I will admit, I didn't compensate for the difference in clockspeed. The E6700 is 11% faster (in terms of clockspeed) than an E6600. So, it actually scales 75%. This is still a bit less than 86%, but not as drastic as 54%. Still, something is clearly slowing it down a tad, but 12% is relatively excusable. Some of that could be the software's threading inefficiency. But still, there is a decrease in scaling (which is to be expected).
