TV Tuner and WiFi can be done well enough via USB (if not better due to convenience, or even a gigabit NIC for that matter), especially once you have USB3.0, which any modern motherboard will include.
I use one for a dedicated Intel LAN card. And yes, I notice a difference from the onboard controller.
Probably not, but onboard ethernet controllers are typically Realtek.Is it different even if tbe onboard controller is an Intel?
