I moved to an Ultrawide a few years ago and would never go back, there can be some steals available now compared to when I got mine. This Odyssey G5 looks good for the money. However I'll always say to do your own research before blindly buying a high ticket item.
Don't have an answer for your question, but... Freestanding is actually considered better, because it doesn't move with the rig incase you're adding some Force Feedback under your rig, to make it move and the monitors don't vibrate together with the rig / wheelbase. You generally don't wan't to cheap out on the monitor stand, as if it fails, all of your monitors break or get damaged. Another thing is, that it looks like your getting 60hz monitors, because I don't know what monitors, that are 120hz or 144hz, cost less than a hundred bucks. For sim racing I don't recommend anything less than 120hz at all... Remember, if you want to upgrade later, you need to buy another 3 monitors. Maybe consider an Ultrawide at this price range, it won't be the same as tripple monitors, but it gets very close. Some people even prefer Ultrawides over tripple monitors, because you don't need to worry about bezels and you can get a stand much easier (and cheaper). For the price you're paying, you can get a [165hz 1440p Ultra wide](https://a.co/d/0djCCSOT) , when overclocked.
