Question Will using capture card as second monitor will affect fps ?

[tagreb2001]

my capture card is capped at 60hz and i want to get 144hz monitor but i can't get 144hz if the cable passed through the capture card so if the take 2 hdmi cables from the gpu as if the capture card was another monitor will this affect the fps specially while recording ?
If yes ,then how much
My gpu is : gtx 1080 ti
Capture device : avermedia live gamer portable 2

I think having the capture card and the monitor plugged together into the gpu is like having 2 monitors one 144hz and the other 60hz but both r showing the gameplay
So if someone have 2 monitors like above or a capture card with nividia gpu can he test and tell me the result pls ?

You should look at the Live Gamer 4K, not the portable capture card.
