FirePro R5000 for Looking Glass Host

I am looking to try to get Looking Glass setup in Fedora 33. However, I need to buy a second GFX card.
I found a cheap FirePro R5000. Looking through the specs left me with questions. Searches have so far proved fruitless. I want to drive 2 1440p displays at 144hz. The DP spec of the card is 1.2 which means it should be capable of it. Does anyone know if this card will work with Looking Glass, and drive both montiors @ 1440p x 144hz?

LG wont capture > 1 monitor at this time.
