USB 3.0 hub bandwidth

I'm considering buying a Lenovo X1 Carbon (1 USB 2.0 port, 1 USB 3.0 port, 1 DisplayPort) notebook as my primary machine. However, I plan on having a widescreen monitor, keyboard, mouse, and an Ethernet cable hooked up to this machine.

Since there's no dock connector on the X1C, I was debating buying this 3.0 dock from Lenovo:

Will connecting this hub to the one USB 3.0 hub give me enough USB bandwidth to hook up the following:
1. USB keyboard
2. USB wireless mouse
3. Ethernet (gigabit port on this hub)
4. DAC

As far as I can find, USB 3.0 has a bandwidth of 5Gbps and Gigabit Ethernet can go up to 1Gbps. Would the actual throughput of the hub be enough to power the DAC (converting FLAC), USB keyboard, and USB mouse? I figure, like with power supplies, this is some sort of math problem.

Any help would be great! Thanks!

Well, USB 3.0 specifications allow for currents up to 5 Amps per port and that should be able to power everything.

I'm surprised that the laptop doesn't have a ethernet port already on the laptop.

But I think you should plug the DAC into the USB 2.0 socket and the rest into the USB 3.0 hub...

I don't see a problem with using wifi for internet since most places doesn't have enough bandwidth reach the limits of the 802.11n...

How much bandwidth do you think a DAC needs? Is USB 2.0 more than enough?

I guess I'm not sure where to find this information.

Hmmm... a DAC shouldn't need much bandwidth at all (since it's just receiving sound signals)

even uncompressed music files are barely over 1-2 mbps...
