Comments
I mostly play Battlefield 4, 1080p, ultra (max), with maxfps configured to 60FPS. Works very good. Drops to 40 during intense smoke and high activity. 

I recommend the X1 Carbon setup and think the Thunderbolt 3 PCI Bus x4 is a must for any eGPU.

The USB ports on the HP Omen Accelerator are not stable. Mouse and keyboard "freezes" all the time. This is consistent with what others are saying on this forum and on the internet.

22. Sept 2018: Mouse and keyboard is now working fine, also when running Unigine Valley Benchmark. See second post here for details.

Drop a comment if you have any questions.

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts
