So about a week ago I posted about the new kabylake g 2 in 1’s coming out.  After some more research I found another build I was considering.  This build would take my current gtx 1080Ti and place it in a Mantiz Venus thunderbolt 3 EGPU, and hook it up to a Lenovo Yoga 720 (15) with i7-7700HQ with on onboard gtx 1050.  I would hook it up to an ultrawide (3440x1440).  My question is do any of you think this would be enough to reach 60fps in most games at high or ultra settings.  I know that that the Lenovo Yoga 720 was found to only have 2xpcie lanes vs 4xpcie lanes which I was under the impression was bad.  But recently I saw some benchmarks he did recently and it seemed that the 2 lanes weren’t a detrimental factor.  Any input on the matter would be much appreciated.

Also I planned on putting an ssd in the mantiz egpu SATA port, not sure if this would affect performance.

Thanks

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

I believe the 1080Ti will reach 60fps Ultra in most games at 3440x1440. More demanding games like The Witcher 3 or X-Plane 11 might not be able to run at 60fps with ultra settings.
Having an SSD in the data port might reduce your bandwidth by some degree, but not by much I believe. 

As eGPUs have a performance drop close to 20%, you could search for Ultrawide-benchmarks of the 1080 on YouTube and see the results. A 1080Ti would perform similar (or even slightly better) compared to a 1080 in a Desktop PC, and therefore the 1080 reviews might indicate what performance you can expect.
Best of luck in your setup/research.

I have a GTX 1080 eGPU (Aorus Gaming Box), a 2011 MBP and a 3440x1440 monitor, and I might post some benchmarks if I get the setup work. (I know the setup is far from similar to yours but might be an indicator).

Thanks for the feedback.  I think I will wait until March for when the new ASUS Flip 15 and the Kaby lake g 2-in-1’s come out, but I am learning more and more with every post.

Thanks for your help!
