Skull Canyon Intel® NUC Kit NUC6i7KYK + eGPU + Which Graphics Card for VR?

Hello!

I was recently gifted a skull canyon NUC (having a 6th gen i7-6770HQ processor @ 2.6 to 3.5 GHz Turbo, Quad Core, 6 MB Cache), 2 180 GB M.2 SDDs, and 2x8GB RAM, and wanted to add an eGPU to see if I can use it for VR gaming both now, and when future headsets with higher resolutions come out. 

I'm new to most of this and tried reading a bunch, and it appears that there are two main issues with my setup, one being the bandwidth constraint of the TB3 connection using PCIe x4 instead of x16, and the other being that the CPU of the NUC will bottleneck higher end GPUs.

Based on that, I wanted to see if anyone was running a similar setup and/or had a recommendation as to what GPU could work in an eGPU enclosure (leaning toward the Sonnet, Razer core X, or getting it all together in an Aorus box).  Would a RTX 2070 be too severly bottlenecked by the CPU to make it worth it?  I'm essentially looking for the highest end GPU that makes sense based on my system constraints of the CPU and eGPU setup.  Thanks in advance!

Unless you need both M.2 drives or the convenience of easy plugging and unplugging of the eGPU I would go with an M.2 to PCI 16x eGPU setup. This would be much cheaper and give better performance.

I thought the m.2 slot in this NUC is also a x4.

The M.2 is a x4 slot, but a proper x4 to x16 adapter has been shown to be significantly faster than thunderbolt 3. This is probably because the data doesn't have to go through a thunderbolt chip that can add latency.

Thanks!  Any thoughts on a suitable card if I go that route based on the cpu constraints? Would a 2070 be too much for the cpu?
