Currently bought a
'GC-WB867D-I Wireless AC WiFi & Bluetooth v4.2 Card, PCI-E'
and so far the bluetooth has been choppy, i dont really care about the wifi portion as i have a wired connection, but the bluetooth is horrible.
Its literally right beside the card and the sound is choppy.
And the wireless and bluetooth drivers are currently updated to 126.96.36.199
Sorry, but this is a gigabyte adapter.
