recommended graphic card for exp gdc 8.5c on ubuntu 20.04

During home office I would like to get 4k resolution from my HP EliteBook 8570p with i7-3520M and 16GB RAM on my 4k 40' tv. I work on Ubuntu Budgie in latest version 20.04.
I have ordered GDC EXP 8.5c with Expresscard cable and after 1.5 months it arrived. Meantime I bought Chieftec A80 PSU to the set.
First I tested my gdc exp with card from my current children PC: Radeon HD7750: but the card didn't start immediately during system booting, switching ATX PW didn't helped. If I inserted expresscard to laptop after boot the card fan started. But Ubuntu Budgie didn't noticed the new card. I also tested it on Linux Mint started from pendrive and it also did not noticed the card.
I'm thinking about buying another card: GTX950 or GTX1050TI: the price / performance ratio seems to be more attractive in the second, but I'm affraid if GTX1050TI would be more problematic. I know about error 43 on windows, but are there additional problems on ubuntu with the 10xx cards? If there is no way out I can buy GTX1060, that seems to be more recommended, but it is a bit more expensive. Or should I buy some card from AMD? What do you recommend?

Regards
Grzegorz

Ps. after the pandemic, I will give new card to my children instead old Radeon Smile

@grzesiek_danowski, if you’re just going to use windows rx 570 will do. I have the same setup through exp gdc and expresscard with my thinkpad w530...

Thanks @a_gay_has_no_name for recommendation, but a few days ago I ordered the GTX 1050TI.

Earlier I made another try with Radeon HD7750 - after adding startup parameters (found somewhere on this site):
 
quiet pcie_ports=native pci=assign-busses, nocrs, realloc iommu=on intel_iommu=on udev.log_priority=3 

the card began to be visible (by lspci), but attempts to switch e.g. using a script: https://egpu.io/forums/thunderbolt-linux-setup/a-script-to-change-xorg-config/ only resulted in no image from both the integrated card and Radeon.

Well, I have to wait for the ordered GTX to be delivered and I will try again :).

Regards,
Grzegorz

@grzesiek_danowski,

if your card is recognized by linux you can try the following which will tell which gpu will run the glxspheres64 program...

DRI_PRIME=0 glxspheres64

DRI_PRIME=1 glxspheres64

Optirun glxspheres64

Primusrun glxspheres64

In my case,

Optirun runs my dedicated nvidia gpu

Primusrun runs my internal Intel HD 4000 gpu

DRI_PRIME=1 runs my RX 570

Note that I'm using bumblebee driver for my Optimus Nvidia Dedicated Card and Intel hd4000.

RX 570 driver is installed out of the box in Manjaro.

So when I run any program I just insert optirun, primusrun or DRI_PRIME=1 before the program name.

What's sad is my fps for RX 570 4gb is capped at 25fps Ultra and high under heaven benchmark through internal display 

I don't use external monitor.

While under windows 10 I get 49fps capped under ultra and high with heaven benchmark also internal display...

It may be easier to setup an nvidia card though goodluck to your upcoming card!

I received the GTX1050TI, but testing the card I get errors:
pcieport 0000:00:1c.1: pciehp: Failed to check link status
The system starts up, but works very, very slowly. Similarly, if I plug the expresscard when the system is already running, the system drastically slows down.
I tried different startup parameters, from those I had with Radeon to the "quit" itself.
Any ideas?
Regards,
Grzegorz
