Nice, I will have to test this out.

Anyway, this next one is for Dave...
If you are setting CPU affinity to only specific cores make sure that you are indeed using the physical core and its correct virtual core counterpart together. In fact, I believe some people had reported with their i7 920's back in the day that they got better results by assigning specific cores instead of all cores across all instances of the game.

And one last thing to try for the hell of it...
Try turning off the Hyper-Threading feature in the BIOS and test it out with just the 4 physical cores. /shrug
