Will my gpu be good enough to stream games?

Context, I have a radeon rx 9060 xt, i bought the new lego batman game a bit back and have been playing it with my sibling. Heres the issue, its on my pc bc i have the most powerful build, they both have gtx smths in laptops that are in need of an upgrade. So, when I want t ouse my pc, they cannot play it, so my plan is to add a second 9060 to my rackmount server (iirc 16 gbs of ddr4 and a ryzen 5 5500), then plug a minipc i used before the rackmount one to run artemis (while the server runs apollo), then run a cat6 cable from the minipc to my gigabit switch, i already have my server on cat6 tho, and i have fiber internet.

TL;DR is a radeon rx 9060 xt enough to stream lego batman legacy of the dark knight

Also side question i noticed my servers motherboard has a second pcie slot, can i use one gpu for games and the other for a local AI?
