BenchZowner -- again, thanks for contributions. As a comparision, I did the same. To ensure no confusion, recall my data is being done on systems with 8800 GTX, Windows XP, thus DX9....

The raw data can be found here: Thread Scaling

Here is the summary info for low res/low detail thread scaling:



Plotted up a slightly different way:


Finally, a table showing scaling factors normalized to a single threaded run for each seen with respect to each CPU:


So here the native quad advantage shows up -- from single thread to 4 threads, the scaling factor of the phenom scales with respect to the single threaded performance better.
