I highly recommend you read the thread on that board. While Asrock Rack has done well in the past this board has had some mixed issues.
There are a ton of x470 boards with 2 nics on it so really all you get is the IPMI and I guess the igpu. You could throw a low power gpu in if you want on any x470 and still have similar experience. If you are set on it, I dont blame you but I was in a similar decision but ended up on an x570 to give me pcie 4.0 for the future (only 2700 in it atm) and the lane spit i wanted and x470 was more expensive.
