What cards(s) I need to be able to output eight 2k monitors using DisplayPort 1.4 daisy chaining ?

Can one card with three DP1.4 ports - be able to output eight 2k monitors ? 

 

Anyone tried in Windows 10 to use  both AMD card and integrated Intel card to output to monitors simultaneously ? ( in Nvidia I believe Nvidia Control Panel can only output simultaneously to Nvidia cards ).

You can use DP output from your video card to a MST Hub that can connect up to 3 or 4 Displays at one time if you are going to be using 2K Monitors.

Many AMD Professional GPU cards supports 4 -6 Displays.

AS AN EXAMPLE ONLY this AMD Radeon Pro W6800 supports 6 Displays:

With 2 DP 1.4 MST Hubs that can connect 4 Displays you will have your 8 Displays. This GPU Card should have no issues with 2K@60hz to connect 8 Displays. I might be wrong but just looking at the Resolution chart in the image above.

But AMD Professional GPU cards are generally quite expensive. There are many Consumer GPU cards that supports 4 Displays that may be less expensive.

EDIT: Reread you original post and you mentioned about Daisy chaining several Displays. Found this Dell Support on how to do that: https://www.dell.com/support/kbdoc/en-us/000128707/how-to-daisy-chain-multiple-monitors-using-displa...

The above article is for DP version 1.2 which has less bandwidth than DP version 1.4

You can't do more than 4 or 6 monitors on a card even if you stay below maximum resolution bandwidth. 

The cards themselves limit it. 

2 cards are needed.

I need two pci x16 slots or possibly two Thunderbolts ports for egpus

True then as you mentioned you would need to find 2 GPU cards that support 4 displays each.

This tech site shows one GPU card with 8 MiniDP ports that each can support one 4K Display for 2022: https://multimonitorcomputer.com/best-8-monitor-video-cards.php

This M9188-E2048F M9188 Graphic Card from link above at Amazon costs $959.00: https://www.amazon.com/dp/B0031KF8AS?tag=mmc-st004-20

Nvidia also has one 8 Display GPU card: https://www.pny.com/nvidia-nvs-810-for-8-dp-displays

This PNY GPU card at Amazon costs $1,150.00: https://www.amazon.com/PNY-VCNVS810DP-PB-Video-Card/dp/B017NL55BM

This has the best 2022 Consumer GPU cards for multiple Displays. A few  AMD GPU support 4-5 Displays: https://levvvel.com/best-multi-monitor-video-card/

So depending on your budget you have a few GPUs you can choose from.
