Now this is what I call fun!
here is my Newegg wish list for the absolute best, "Incredible overkill", "Balls To The Wall" desktop PC!
The ASRock X79 Extreme11 LGA 2011 is the Absolute Best, Fastest, "Incredible overkill", "Balls To The Wall", Mother of all Motherboards on planet earth. (check out the links) Even if their are other motherboards that can slightly best it in pure OC potential there is also a lot more to a super fast PC and this motherboard has it all!
ASRock X79 Extreme11 LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 SSI CEB Intel Motherboard __________$599.99

The reason I don't choose a Dual CPU motherboard besides the fact that no motherboard can come close to this one for sheer features is because all the LGA 2011 dual CPU motherboards use Xeon's and Intel is not (at this point) making any that are overclockable so 99.9% of your applications would actually run slower since they don't have the ability to use all those cores anyway.

This is the best (maintenance free) closed loop water cooler with better cooling than any air CPU cooler. However if you want the best and you don't mind some periodic maintenance, a custom watercooling system with the ability to cool other things like GPU's, chipsets and mosfets and also cool your CPU better is the way to go.
