First I'll start with the CONS: The 1660 Ti model is not a 144hz display as advertised, it's 120 (Amazon has since updated this to reflect accurately). Screenshot included. I mostly play older games (A few from 2017 but most older than 2011) and many have had compatibility issues with the 120hz display in this. Many have required convoluted workarounds to get running. Even when plugged into an external source like my 60hz 1080p TV I cannot get them to work normally. If somehow I do get the incompatible games to play they will slow down and play at 50% speed at 30fps or double speed at 120fps. Only one game I play is new enough to take advantage of the 120hz and I barely notice the difference from 60hz. You can also not set this display to 60hz, only 120 and 48. I imagine the 120hz refresh rate would be noticeable for newer FPS titles but for the platformers I play it's been negligible.My second issue is the speakers. They. Are. Abysmal. I have heard better sound coming out of a cheap children's toy. They are tinny and high pitched whiny at best and sound very echo-y. Even with the included Nihimic sound tweaking software I cannot for the life of me get them to sound satisfactory. They are also located on the bottom of the laptop which adds to the awful muffled sound even when sitting on a flat surface. My former cheapo 2015 Acer laptop and my extremely old 2012 MACBOOK sound way better than this.My final big issue is battery life. I understand gaming laptops have never been good on battery life but this one, or at least mine, only lasts about an hour unplugged regardless of what it is doing or how many background processes I shut off. The very first thing I did with this when I unboxed it (after letting it charge to full before even turning it on) was run the included MSI Dragon Center software and used the battery calibrate function to improve battery life. Well clearly it didn't help. I can't even have Chrome running something on Hulu or Youtube without draining roughly 1% per minute! And to run a game? Forget about it, you get maybe 10-20 minutes of a non-demanding (that is to say one that doesn't even make the fans kick up) game before this thing is dead from a 100% full battery charge.One minor issue is the USB placement. There is only one on the left and two on the right at the very front. If you plug anything into either of those it often gets in the way of moving your mouse around. Tolerable, but quite annoying unless you're playing on a spacious surface and can stretch your arm out a bit. The AC adapter plug is also in the middle of the right side and can get in your way as well. The cord for it is very thick and sticks out about 1" from where it plugs in. The charger's power brick is also a massive 6.75" x 3.5" x 1" and a bit awkward to travel with.The fans can run pretty loud especially if you hit the turbo cooler button but this really doesn't bother me, nor do I really play anything that makes them kick up too much. They can be loud enough that it sounds like someone is running a hair dryer or vacuum in the next room over. So if you'll be gaming in a place where it's quiet, like a library or college, people around you WILL notice the sound. World of Warcraft on all max settings is as strong of a game I will ever play on this. The fans only kick up when a lot of effects are happening on the screen and it only maintains an average of 85fps (45 in a raid setting with many spell effects going off) with these settings. Completely unnoticeable difference from the 60fps of my other computers.Now onto the PROS: The hardware itself is extremely powerful for the price and the build of the laptop is top notch. The lid and screen are encased in metal while the bottom is a fairly sturdy feeling thick plastic. The screen does not feel flimsy or jiggle when being opened or getting jostled. The laptop itself is a gorgeous work of art and the included software for the Per-Key lighting is fun to play around with. You can even make different lighting profiles for every single program that it will automatically switch to using for whichever is running in the foreground. The MSI Dragon Center software is also amazing. It can monitor everything inside your PC, things that you'd normally have to check in the BIOS or use another program to monitor. Like fan RPM, CPU/GPU temps, how much RAM/CPU/GPU power is being used ect. It can also keep all your most important drivers up to date with one click in addition to a plethora of other handy things. It also lets you tweak those settings for everything it monitors.The internal webcam is of decent quality and the internal mic is also pretty decent as well. The keys have a great feel and response to them, as does the trackpad. One thing I really like is when you hold down the Function key it highlights the keys you can use while holding that button down.If you are planning to only play the latest AAA titles and FPS this would be a great buy. However if you're like me and enjoy the older games on Steam/Uplay ect you may find yourself frustrated quickly. You may want to also consider having a headset or bluetooth speaker to pair with this since the internal speakers sound nearly ear-bleed worthy.UPDATE: I decided to keep this laptop after not being able to find a satisfactory replacement in the same range. I have made quite a few improvements since my first review roughly a month prior. I discovered the terrible sound was because of the Nihimic sound program. Once I shut that down and let the default Realtek audio driver control it the sound is completely fine now, no more tinny awful ear-bleeding sounds coming out of my speakers. Do yourself a favor and delete that trash Nihimic program. However the speakers still sound muffled being on the bottom but sound much better when I have the laptop elevated a bit in the front. Many of the older game incompatibility issues I was having have slowly been resolved with a lot of extra tweaking and work. Some games however still will not work correctly, nor do I believe they ever will. Other than that I have honestly been loving this laptop the more time I spend with it. I'm able to look past it's few terrible design flaws (speaker placement, usb placement, charger plug placement, awful battery) but they are always going to be a constant pain in the butt I can live with. I even contacted customer service about the speaker issue and they got back to me fairly promptly and were very courteous. Although with the poor speaker placement and terrible battery life I still find myself bringing my MacBook instead to play music and video when I am up and about and not planning to game. This laptop basically needs to be plugged at all times...kind of defeats the purpose of a laptop wouldn't you say? My battery also won't charge to full even though I have the battery profile set to do so. I plan to contact MSI about the junky battery next.
