thinkpad X1 extreme with Akito node and 2 SSD: feasible or not

I have Thinkpad X1 extreme with I7-8750, 16GB RAM and  Nvidia 1050TI Max card with 4GB ram. I wanted to connect e-GPU like Akito node, with Nvidia 1070,8gb RAM.  I had following questions:

  1. Reading a topic on This website,  NVMe flash storage drive gets a x4 PCIe connection. The Wireless card can get a connection, so will 1050 card. So, my question is, If I upgraded my laptop with another NVME SSD, would I be out of PCIe connections, for connection to a EGPU?
  2. Would it be possible to use both external GPU like 1070, within a Akito node, alongside the dedicated 1050 card, or would the drivers for 1050 would need to be removed and new card added. Could it lead to problems where I wont't be able to use my dedicated 1050 Ti card? Then, probably isn't it better to get no dedicated GPU laptop and hook it with EGPU. But the problem I see is that most of the laptops with i-78750 already have a graphics card. if I go lower to 4 core, I am not sure it will help with my requirement, which is deep learning?
  3. As I mentioned, I intend to use this for deep learning. Now, I understand that there can be 20-30% reduction in performance with E-GPU. still, from 1050TI to 1070 and with 20-30% eGPU reduction, I should still expect 60-70% performance improvement?
  4. If I buy laptop like MSI stealth 65 or razer balde 15 with higher graphics, I don't get good battery life/chunk keyboards etc, and if I move towards Surface Book2, that is very costly. I read that Thinkpad X2 extreme is soon coming with GTX 1650. Any one know would it have an option of 1660 Card too?

I have a week before my return window for this laptop closes, so any response would be appreciated.

Hey! I can answer some of this.
I added a 1TB NVME SSD and it doesn't conflict with my Node. Regarding your second point, you can leave the 1050 Ti enabled alongside the 1070, but you may run into issues. It would probably be a safer bet to disable it when not needed and enable when you do. Uninstalling the 1050 ti drivers is probably unnecessary.

Hi  YourLittleInnerFight,Thank you for the reply.Some follow up questions.
Did you install 1TB SSD in second slot, or replaced the original one?
Do you have any writeup or some link to steps you followed with Akito Node? On akito website, they dont show compatibility with Thinkpad x1 extreme.
Regrading your point about enabling and disabling the 1050 TI, is there a app or something that does that, and is it painless?
btw, what graphics card did you install and how much performance improvement you saw?

I installed it in the second slot. 

Myself and a few other users around here have this setup, and it works fine. Akitio likely just hasn't tested it themselves. Their own guide is a bit barebones but functional.

I installed a 1070 myself; it depends on the program, but the boost ranges from about 35% in poorly optimized programs to probably 80% in better ones, with most closer to the latter. I have no experience with deep learning however, so I don't know how much of a boost you would get there. 

Regarding the 1050 ti, you can go to your device manager and right click--disable/enable. You shouldn't need to do more than that.

1. No . I have two NVME installed on my X1 Extreme. Works fine
2. My 1050Ti is still there for some of the computational stuff you can even get 1050Ti to do tasks. Not an issue at all . Just need DDU to delete Lenovo drivers , install stock nvidia drivers and it works 
3. Should get an RTX. Fun fact is that you should be getting as close to desktop performance. I would say 90% of 1070. You should opt for RTX cards instead if you can afford
4. No idea
