  1. Hi everyone. New to Tech Inferno. You can call me Stu. Nando asked me to post my setup and results which I'm happy to do. I'm going to keep this as simple as possible since this eGPU project has been just that, simple and awesome. In my eyes, this is where the eGPU game ends. Thunderbolt 2 (and TB3 coming soon), full-size chassis, fastest single GPU on the market, running at desktop speeds. I suppose the only caveat is cost but considering I only need to upgrade my GPU from this point on, it’s worth it. I live an hour away from Sonnet's headquarters in California and decided I had waited long enough to complete my eGPU experiment. The results surpassed expectations. Feel free to scroll down for specific benchmark and game results. Key Points Completely plug and play. Standard Bootcamp 5.1 install (*see below), connect everything up, boot Windows, install drivers, you’re done. eGPU vs Desktop performance: 85-90% Gaming: Max out virtually any game. 60FPS+ (with a few exceptions. e.g. Black Flag has weird PhysX that kills performance so I turn it off) Discrete 750M graphics = No Optimus/Internal display support. MBP w/Iris only = Optimus support but not fully plug and play (**see below) Simulated Optimus FPS loss: 5-20% (window drag method) eGPU Setup Cost (Not including MacBook): $1500 to $2000 depending on GPU purchase *It appears only 2013 MBPs w/newer PCIe flash storage defaults to UEFI/GPT-based windows installation with Bootcamp 5.1 .. 2012 rMBP (and possibly other macs/notebooks) will not format to GPT and therefore no plug and play **Conclusive Results for 2013 13" MacBook Pro - Optimus - Thunderbolt 2 - Plug and Play Configuration 2013 Macbook Pro 15” w/GT 750M [email protected] 16GB-DDR3L 512GB SSD US$2599 Sonnet Thunderbolt 2 III-D Chassis (US$979) EVGA Nvidia Geforce GTX 780 Ti Superclocked 3GB (US$720) Corsair RM450 (Silent) Power Supply (US$100) for 8-pin cable only (Jumped the 12V rail with small piece of metal.
