Looking at your vcore and overall speed, it's pretty clear that one of these 45nm chips would basically pee all over my q6600, particularly with this board. I'm struggling with 462x8 and on 1.48v. Makes me think how much electricity I could save too!
Think I'll get a Q9650 after my OCZ blades, and will hope to have a nicely tuned, quiet, low voltage rig when I'm done
