An Intel branded NIC comes with either board, so that's good. The UD5H comes with a bonus 2x USB 3.0 front port bracket, so that might be a deciding factor.
Also: Gigabyte boards are usually better supported for creating a Hackintosh, if that's a possible planned configuration.
No problems with Realtek here :whiste:I was hoping someone would mention the intel branded NIC... thank you sir. Best post of the night, imho. Screw Realtek NIC.. bad drivers.
