? the GPU have default nothing todo with this issue.
USB Devices need Bandwidth most consumer systemns Have 6-8 USB Ports but mostly only 2-3 Real USB connector splitted with hubs to the 6-8 Ports.
the real avaible Bandwidth is only 2-3 related to the hardware setup
so you can not Install 6-8 Cams only 2-3 related to the avaible.
to add move you need to bring additional USB Bandwidth in to the system with PCI-E Extension cards

This has nothing to do with your GPU. Every USB device needs USB bandwidth, so if you put them all behind the same hub, you get bandwidth issues.
Distribute your camera devices over as much USB root hubs and host controllers. Don't put them on the same external USB hub you might have bought.
USBView can help to identify available root hubs and available controllers:
