I don't know Zyb. I just paid:
CPU INTEL|C2Q Q6600 2.40G 775 8M R 1 $209.99
The Phenom was more, I priced them.
I built this thing last evening/this morning and all I can say is wow! I'll OC some more once I study this board. DFI makes some great boards but I hate a no boot situation with this thing. I have to pull the bottom card, remove the battery, reset both jumpers or it will not boot. I do have a back-up in the CMOS that will boot and allow me to reset defaults and start over. Hotkey 1 on a no-boot and you have a 50-50 chance of getting lucky. If not..........

.
Like I said, I need to study this bios. It ain't easy but 3.6 is a possibility.
I have some early benches like 17000+ in 06 and 7000+ in Vantage but I haven't figured out where I am with this rig yet. I know I can push further than where I am. Time will tell.
