Compared to a PCIE ethernet card or the built-in motherboard ethernet port, how much additional latency, if any, would a wired USB 3.0 network adapter such as this one introduce?

Also, how much additional CPU overhead, if any, would a gigabit USB 3.0 adapter require to operate at full speed?

EDIT: Oops, the title was truncated. That's supposed to be "CPU usage", not simply "CPU".
 
I have a Dell version I use with my XPS13 and it isn't noticeably different to having an on-board NIC.

I've never directly compared it to a real NIC as the only time there's any reason to use one is when it's the only option available.
 
Minimal, generally use onboard unless you have a specific need to use something else/it's crap, if you have a specific need then you will usually have a list of pre-qualified cards that work with whatever you need.
