Gamer GPU vs. Professional RTX4500 / RTX A5000 / RTX4090

Hello,

I need some insight in the difference / advantages / disadvantages of Gamer vs professional GPU´s.

As far as I understand the Professional GPU´s can utilize a Quadro Sync card for multiple displays.

I need to run one HD / UHD LCD display, maybe 2 HD displays (one for ceiling, one for background) and I am trying to find a suitable PC setup. No deed to drive a large LED volume.

Thanks,

Robert
