Hi Ed, do you see a noticeable improvement on your Mac?

You can get some actual numbers by setting up the following on a shortcut key, then pressing that will show the redraw time in the upper-left corner of the viewport window:
script: /* Toggle redraw time display */ moi.ui.showViewportDisplayTime = !moi.ui.showViewportDisplayTime;

Then with an actual number on the old one and a new number it's easier to tell exactly how much improvement there has been.

Also, what kind of CPU and video card do you have on your Mac?
