Comparing the spec sheet to Newegg, you're paying around a grand more if you buy that package. Is there a reason Pro Tools works good with an $1100 CPU and a $35 GPU? The processor is a beast but it is not 3 times as good as a $300 4790K, especially not if you overclock it.
Audio processing, according to an architect at Logic and an architect at Avid, is all about physical cores times clock speed. This is why my 8-year-old 3.2gHz 8-core is so much quicker than anything new. Unfortunately, the rest of the computing world is not so constrained. As such, architecture has shifted away from optimal from an audio standpoint.
If you didn't have the real time constraint you could benefit from using the GPU, but it would be really hard to do that and do the processing in real time because you'd have to send large buffers to the GPU and fetch them back to get any benefit. Not impossible, probably, but hard.
