Any opinions on this monitor for casual gaming? It would be the third monitor; I'm using a pair of Asus 4K monitors for work stuff; this would pretty much be dedicated for gaming, primarily FPS games.
it seems fine, but I would opt for one of dell's 144hz monitors if you have an nvidia GPU
Since you play primarily FPS games I would look at a 1080p 240hz monitor. I just picked up a 1080p 27" 240hz monitor for $280 USD. It feels amazing to use and my tracking is 100% better. I don't like 1440p since I feel like is doesn't provide a better picture over 1080p (at least as noticeable). Depending on the GPU you have and the budget you have you can probably get one with the V-sync of your choice.
