Well after a week or so I have to say....the new i7 860 is a dream come true!
I have not really figured out the "turbo boost" yet. I have Intel's "throttle down" options turned off for now and with turbo boost on, it idles at about 3Ghz and goes to about 3.4 under load.
It overclocks better than I would have dreamed. I am glad I didn't get a 920 now. I came very close. The 920 is fine but I'm having more fun with the new 860.
The P55-UD4P Gigabyte is a fine motherboard. I have nothing bad to say. I wish there was a power switch on the board as I spent a couple of days on the bench but it's in it's home now and works great. All the other features more than make up for no power switch.
The Mushkin 1600Ghz 7-8-7-20 memory is better than I thought also. I am very happy with the whole setup.
If you're looking to upgrade, take a look at what you can get from the P55
