I upgraded to this monitor from an older TN 144hz ROG Swift 1440p Monitor. Like others, I was concerned about the drop from 144hz to 120hz, since I'm very sensitive to that type of minutiae, but I haven't found it to be an issue. I can tell, slightly, but the difference is minuscule, especially compared to 60hz vs 120hz.Here's some quick Pro's:1. Color is fantastic. Obviously going from a TN panel this is the first thing I noticed. I do a lot of photo collage to make paintings from, and this monitor is as color-accurate as I could want.2. 120hz is perfect for a monitor like this. Most newer titles won't run close to 120hz, even with a 2080ti (Metro Exodus with RTX most notably), but when you do hit that sweet, sweet native refresh rate (Doom Eternal) it's mind-blowing.3. Ultrawide makes immersive games even more engrossing. I held off on playing Metro Exodus for a year until I could upgrade my rig and play it on this monitor with RTX enabled. I'm glad I did, because the experience is incomparable to a typical 16:9 viewing ratio. Having the screen extend a little further into your peripheral makes game worlds feel more convincing. From a practical standpoint, having more screen real-estate in shooters, especially something like Battlefield 1 or Doom Eternal is so helpful it can feel like an unfair advantage. So, in conclusion, ultrawide benefits narrative, immersive games just as much as fast, twitchy shooters. No complaints.4. Gsync is 100% worth the price premium. I know people are divided on this, and it seems that more and more monitors are gaining Gsync compatibility without the hardware (not sure how that works). No screen tearing without input lag is just a necessity for me at this point and it's made a lot of titles easier to play, especially ones locked at 60 fps on an engine level.5. I'm a fan of the design, and if the lighter-colored back of the monitor bothers you, I haven't seen it once since setting up my desk. The monitor controls are fairly intuitive to use, but I still prefer the ROG Swift's little joystick knob controls. Bad monitor controls are just par for the course for some reason, so I can't really knock Alienware for this.6. Out of the box, the default settings were nearly perfect. I didn't have to tweak too much to get the brightness/contrast/color to where I wanted it.7. If you do any sort of work on your computer, such as video editing, photo editing, etc, having the extra screen space is a game changer.8. Price. I managed to get mine for around $950ish earlier this year. That's a really fantastic price for the feature set here, in my opinion.The only cons I can really come up with might not be an issue for you. The monitor obviously takes up a ton of space, so make sure you have a desk that can handle it comfortably. It's not no much the depth as the width. Most new games are easy to play in Ultrawide, and they have native support in the game menu, but a LOT of older titles will require tweaking. It's not as big of a deal as the internet would have you believe, as most games I've played do have a work-around that isn't complicated to enable, but I have found some games that aren't compatible, period. Prey, the 2006 version, is unplayable at Ultrawide, unless you can contend with a severely stretched image. That's one of my favorite games ever, so it is disappointing. Point is, if you hate finagling with config settings to get a game to work, this monitor could prove to be annoying. If you're a PC gamer though, this shouldn't be new to you.Overall, I have no real complaints about the monitor. 3440x1440 is perfect, 120hz is great (144hz would be better, but what are you gonna do), the color is vivid and accurate, setup is easy, and your gaming and workstation experiences will be better for owning this monitor. Just make sure you have a fairly beefy GPU if you want to run newer games on the highest settings.
