Yeah, with that setup you're going to be fine.
Little worried about that I7 860. Isn't that the one thats based off of LGA 1156? If so then it only has a dual channel memory controller to work with, not a triple channel one. Therefore you may get some benefit from taking a stick of RAM out and running 4GB in dual channel mode instead of 6GB in single channel mode. If you had a full fat I7 on 1136 then it would be fine because they'd be running in triple channel mode. Just a suggestion.
