Hey, it sounds like you want the same things as me. I do music production, flight sim enthusiast, gamer...
I haven't gotten this computer yet...but everytime I look at this build I get that warm and fuzzy feeling and I've vetted it with this forum's elite crowd.
The geforce 670 is just about equal in strength with the 680. In the future if you want to add another GPU you can do so easily.
Also really consider the Noctua. It's won a bunch of awards, it's quiet...and you don't have to worry about liquid cooling maintanence. Lastly unless you are computer savy I would let DS do the overclocking...
Good Luck
