Along these lines, I was also curious about the quote "the kind of CPU I could buy for cheap would be comically underpowered compared to the i7 4850HQ I already had in front of me" Specifically: will the high-end i7 in a MBP run at Full Turbo indefinitely, or does it throttle down hard after a couple of minutes at full load to avoid overheating, like the one in my Dell Precision does? I'm suspecting the latter, due to the basic physics of heat dissipation from a high-TDP chip. In this case, a sub-$200 Haswell i5 will run circles around it.
