For a balance of performance and portability with a high-quality display suitable for engineering tasks, the Lenovo Yoga Pro 9i is a strong choice, offering a newer GPU and a high-resolution Mini LED screen with excellent color coverage. However, it's less suitable for intensive gaming despite its good general use performance. The MSI Stealth GS66, on the other hand, is designed with gaming in mind, featuring a powerful GPU and a high refresh rate screen, but it's bulkier, has a shorter battery life, and the display, while good for gaming, isn't as impressive for detailed engineering work. If gaming and performance are your priorities and you don't mind a larger, heavier laptop, the MSI could be the way to go. Give Feedback

Florian Glaser | February 2022
"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
