I figured it would be cooler because the GT750 was taking some of the load? Or would the card just be disabled?

Thanks for the tips! While we're on the subject, I was curious about why you picked the iris model with 2.5 GHz instead of 2.2? I imagine the 90 dollar boost is worth it whereas the 200 dollar boost to 2.8 wasn't? It seems like undervolting the 2.5 should give a bigger boost than undervolting the 2.8, since the 2.8 is already pushing the cooling a bit far? Incidentally I'm pretty excitedly reading that recent post about getting the nvidia 750m model to work with iris pro and egpu. Maybe that would provide the necessary coolness?

I am aiming to replicate Dschijn's 15 inch setup. He seems to be using the 2.5 ghz cpu, but it seems as though there's a big boost from the 2.5 ghz 4870 to the 2.8 ghz 4980 I think the same may be true for this year's 15 inch, so I'm wondering if I should splurge to upgrade all the way to the 2.8 ghz iris pro model for that extra physics score boost? Or will the CPU strain only a worry for the 13 inch MBP and lowering voltage as Dschijn does would take care of any demanding processor applications? I was also curious, offhand, what kind of weight this setup might have? I was mostly considering eGPU for portability versus a hackintosh, but it looks like they may end up weighing the same given the weight of the raven's case.
