Olivier Martin, Ryan Lim, and John Peroramas | April 2023
"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."

"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."
