Reply to Haswell rMBP w/ Traktor

Now that we have the new Haswell powered rMBPs, do anyone have any idea/info about how they fair w/ traktor?

I'm curious cause Haswell is all about efficiency and saving power, one of the ways they achieved this is by switching b/w power states. Now anyone trying to reduce audio dropouts and glitches would know that switching b/w power states/frequency can actually cause a DPC spike. Also the fact that this cpu has the Iris pro gpu inside it, I'm kinda worried before I put my money on this new machine.
