I've got the Samsung Odyssey G65B 32". Upgraded from a 165Hz IPS AOC AG271QG. So far so good. It's definitely much faster response time and it's so smooth as long as I can maintain the FPS high. Though mainly the colors and contrast stand out the most. I was worried about QC issues but did not notice anything out of whack yet. The only annoying thing which I'll probably never use is the built in Tizen OS to make it work more like a TV. I think that's just unnecessary. I did not even bother to connect it to network.
A bit of cable management is an understatement. Half of the dreaded cables are barely long enough to reach from PC and UPS so I can't reroute them and the other half is so long that I have them cover floor behind PC like a snake nest.
Get custom cables, zippable wire covers, and lots of velcro. That's what I did and it's SO helpful.
Will do in time. It honestly does not matter to me that much it's just more convenient to clean around once you have it tidied up. So in my priority list it's somewhere in the middle right now.
