Great to see eGPU forums really starting to pick up like this. It seems like more and more people are becoming aware of the viability of setting one up for themselves. I myself am highly considering a setup virtually identical to @boony1's, except possibly with a different version of the GTX 670, and a Sonnet Echo Express Pro instead of a TH05 (The Sonnet costs way too much but I like the overall aesthetics and personally, I don't see Intel allowing the release of the TH04 any time soon.) In any case, I was wondering whether or not I would get significantly better performance with an external monitor? If so, what kind of performance are we talking in relation to games like Crysis 2 and Battlefield 3? If so I'll probably set up the eGPU in a Sonnet with the rMBP, and then a run a DVI to Mini Display Port adapter from the GPU into an external 2560x1600 monitor.
