I'll Post my benchmarks, as I'll be collecting them anyways.
Big thanks to the STEP community. I hope to finally have a stable Skyrim install play though (or as far as I get until my char dies again)
Set up is a MacBookPro early 2014 model, with an eGPU plugged into a thundertek PCIe to Thunderbolt 1 card.
2560 x 1600 display
GTX 760 (no over clocking yet...)
Intel Core i7-3840QM 2.80GHz
Performance benchmark at step 1.F in the step instructions.
Note: I'm having trouble formatting the data into the openoffice spread sheet. for now I'll upload what I got, and once I got the spread sheet figured out, I'll post a nice picture and all that stuff.
