Looking at your results, I guess you have much more processes running than is really necessary. Your MPEG encoding times are far worse than I would have expected at the clock speed you are running.
Check with Process Explorer that you have not more than around 40 processes running before starting PR or AME. Check that you have compression and indexing turned off on all your disks, that sidebar is not started and that your services are in line with Windows 7 Service Configurations by Black Viper

Even when I got the process count down to 34 processes and compression and indexing turned off and the configuration set to Black Viper's "Safe" configuration (which I used for now), I still get the same PPBM4 score I had been getting with all of the default processes running.
Perhaps this may be because I was/am using an ATi card (an HD 5770, at that)? (In general, the consumer ATi cards do not perform as well in OpenGL mode as NVIDIA's consumer cards do.) I am suspecting this because the HD 5xxx series - at least with the drivers that are currently available for them - perform rather poorly on some of the critical 2D tasks compared to the older cards or the NVIDIA cards.
Or maybe it's the fact that I am also using the same editing system for other uses, such as gaming or as a media center? The software used in such systems also adds resource-hogging processes (much of which can't be disabled or uninstalled without screwing up those programs).
Even after this lackluster MPEG encoding performance with standard-definition material, I would have to say that transcoding 1920x1080/59.94i Cineform AVI files to Blu-Ray-compatible H.264 AVC is about 20 percent faster in CS5 than it was in CS4 or Vegas.
