This means that the screen can update up to 240 times per second, making it ideal for fast-paced games where every frame counts.

Overall, the display on the MSI GS66 Stealth is an excellent choice for gamers who want a fast and responsive screen. The 240Hz refresh rate and 3ms response time make it ideal for competitive gaming, while the 100% sRGB color gamut ensures that you’ll see vibrant and accurate colors.

Keyboard and Touchpad

The keys offer a satisfying clicky feel with good travel distance, making for a pleasant typing experience. The RGB backlighting is vibrant and customizable, allowing you to personalize the keyboard to your liking.

The touchpad is also quite impressive. It’s smooth and responsive, making it easy to navigate the desktop and use multi-touch gestures. It also features a dedicated fingerprint reader, which is a welcome addition for added security.

One thing to note is that the keyboard layout isn’t quite standard. Some keys, like the arrow keys and the function keys, are slightly smaller than usual, which might take some getting used to. This isn’t a major issue for most users, but it’s worth mentioning if you’re particularly sensitive to keyboard layout.


The MSI GS66 Stealth packs a punch when it comes to performance. Powered by the latest 12th Gen Intel Core i9-12900HX processor and an NVIDIA GeForce RTX 3080 Ti graphics card, this laptop is capable of handling even the most demanding games and applications with ease. In our testing, we found the GS66 Stealth to deliver smooth gameplay at high frame rates, even at 4K resolution.

The laptop’s 32GB of DDR5 RAM and 2TB of PCIe NVMe SSD storage ensure that everything runs smoothly and efficiently. The high-speed storage allows for quick loading times, while the ample RAM allows for seamless multitasking. We were able to have multiple applications open at once, including demanding games, without experiencing any lag or slowdowns.

During our stress tests, the GS66 Stealth remained cool and quiet. The laptop’s advanced thermal design, which includes a vapor chamber and six heat pipes, helps to dissipate heat efficiently. This is especially important for a gaming laptop, as excessive heat can lead to performance throttling. The GS66 Stealth’s cooling system kept the laptop running at optimal temperatures, even during long gaming sessions.

Overall, the performance of the MSI GS66 Stealth is exceptional. It is one of the most powerful gaming laptops on the market, and it is capable of handling anything you throw at it. Whether you are a casual gamer or a hardcore enthusiast, the GS66 Stealth will provide you with an incredible gaming experience.

Battery Life

The MSI GS66 Stealth boasts a solid battery life for a gaming laptop. While it’s not going to rival an ultrabook in terms of longevity, you can expect to get through a full workday or several hours of gaming on a single charge. During our testing, we found that the laptop consistently delivered around 6-7 hours of mixed usage, which includes web browsing, light productivity tasks, and streaming videos. For gaming, the battery life drops significantly, but you can still expect around 2-3 hours of playtime depending on the game and graphics settings.

It’s important to note that these are just estimates and actual battery life will vary depending on individual usage patterns and other factors. For example, if you’re using the laptop at its maximum performance, you can expect battery life to be shorter than if you’re using it at a lower power setting. Overall, the MSI GS66 Stealth’s battery life is a good balance of performance and portability, making it a great option for those who need a laptop that can keep up with their busy lifestyle.
