The 'Gaming' suffix on this board is obviously silly and is best ignored. The whole TR platform is not a 'good value proposition for gamers' because gamers aren't the target audience.
Its a workstation/home server/networked renderbox platform which is where the use-case value is at. For 32 cores of Zen goodness, 10gbit and decent...ish power delivery these boards and CPUs are actually remarkably cheap, compare for instance to a dual-socket, 2x16-core Intel setup.
AsRock's likely reason to stick 'gamer' on there is its associated with the Fatality brand, which they are apparently set on pairing with 10GBit controllers.
The gaming and windows benchmarks don't really agree with the 2990WX, this is known from previous reviews. Windows doesn't properly work with anything over 16-cores and ffs, don't buy a 32-core CPU for playing some vidja games.
That all said, I do think this board would have made more sense without the extraneous features. The wifi and gaming-ish features are kind of extraneous.
