Thank you. I've read through all Mac related implementation guide within the community. With thomas_prince1 having the highest 3dMark scores through and identical setup. But there seem to be errors appearing on iregret's setup. Likewise, eGPU may not boot every time. Hence my hesitance to shoot for the eGPU. I understand iregret will be reinstalling the Nvidia desktop drivers and I'll definitely keep an eye out for his/her progress. Again, I think this community is awesome. But with my habit of upgrading within 2-3 years, upcoming release of Skylake and Thunderbolt 3, probable stability issue and unconfirmed future of eGPU, it does make me wonder if I should take the conventional PC approach. Really a toss up between footprint, cost, stability and longevity.

Hey folks! Utmost respect to the community for its advancement in eGPU technology. The discovery of Akitio Thunder2, removal of powered riser, and most recently PCIe pin cable to 12v dc barrel possibility in a span of 9 months. My only objective is to run graphic intensive games smoothly at High/Ultra settings on a 1080p external display in Windows 8.1/10 for the next 3 years with minimal tinkering. I have limited time for gaming, hence only select titles. Otherwise, I have no need for a PC or an eGPU. I was ready to shop for an eGPU until the recent surge in eGPU troubleshoot in the community. A conventional PC setup appears to be more stable. 1. Should I pursue an eGPU or should I shop for a PC instead? 2. Can I use the following parts?
