If you look only for a CPU model (frecv, cores and so on) you risk to make a disequilibrate computer, you need to coordonate a CPU with speed of RAM, speed of GPU and the spped of HDD to avoid bottlenecks.
So the CPU it self not say much about a computer and his capabilities.

NICE, I like, more....

For me this is how it worked

Like anyother with this error, wired network was on "en1" and wifi was on "en0", so after reading a lot of www pages with solution this is what worked for me

1. removed all interfaces from system preferences->network
2. deleted  "/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist"
3. edited org.chameleon.Boot.plist with <key>EthernetBuiltIn</key>
   <string>Yes</string>
I tryed without but not working
4. rebooted
5. added interfaces in system preferences->network in this order, first Ethernet and second wi-fi

PS. You have to have a kext for your wired ethernet card in S\L\E, I do not needed any key with "systemid" or "device-properties" keys  in my boot plist, but I have a corect serial number in smbios.plist

6. After my EXTRA was OK I use this terminal commands to copy extra to "Apple_Boot Boot OS X" partitions from my RAID 0

diskutil list  [Enter]   to see what numbers I use on X in diskXs3 commands   

diskutil mount disk0s3 [Enter] (First drive in Raid)
cp -R Extra /Volumes/Boot\ OS\ X/ [Enter]
diskutil unmount disk0s3 [Enter]

diskutil mount disk1s3 [Enter] (Second drive in Raid)
cp -R Extra /Volumes/Boot\ OS\ X/ [Enter]
diskutil unmount disk1s3 [Enter]

My tutorial to make raid was from here

mine look like this, my ideea is this info is only standard, no matter what card you have, i think is coresponding with what chameleon give to OS, or DSDT.aml

I see now, my contrib was indeed edited, in my opinion it was unnecesary because I think the hole reason of wiki is to lead everyone to a good config for a working machine, despite the source of the software (if is free). I not want to imply you should be agree with me, and you should let link to (t word), I am aware of the competition on web after audience, publicity, notoriority and so on, but like I say befoure I think final result is much important than ways to get there (in this case).
