Marc Herter, Alex Wätzel | November 2023
"The new Zenbook Pro 16X is more powerful, quieter and doesn't need to shy away from dedicated workstations and gamers. It is also comparatively compact, and our test device is the best Zenbook that we've reviewed so far. It seems equally suitable for content creators and gamers or anyone looking for a very powerful laptop that is still slim."

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."
