Hi Friedric
Your new rig looks killer
I put together something very similar the other week, typing on it just now, went for the slightly faster I7 3960 E and also the Asus Rampage Extreme IV clocked to 4.6GHz, its mainly for FSX as this sim will use all six cores but CLOD flys on it too, this system is much quicker than my previous I7 2600K overclocked slightly higher ... I even have the same soundcard (Asus Xonar STX) as you, running a GTX 680 though, running a Corsair H100 for cooling too.
Enjoy.
