However, I didn't really intend to post it because a) it was relatively difficult to try and get the SB processors on a level playing field with the other chips, since it has less adjustable multipliers/frequencies, and b) because from what I can tell, disabling EIST & C1E seems to have a slightly greater performance impact on SB chips than the others.

The above table also can't take into account whatever performance gains will be had when AVX comes into play with the release of the SP1 for Win 7.
