I had an extra Xeon X3450 CPU, so I swapped the I5-660 for the Xeon X3450 (quadcore w/ hyperthreading). I didn't need to make any system changes and no CLOVER config.plist changes. The system booted fast and Intel Speedstep / CPU Power Management continues to work perfectly without enabling Generate C/P States in config.plist. Even though the X3450 doesn't have AES-NI instructions like the I5-660, system responsiveness is much better than with the I5-660 (I'm running High Sierra HFS+ and not APFS). A Xeon X3480 might be a good upgrade if prices continue to come down on Ebay.
