Rtings

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."

PCMag

Brian Westover | August 2023
"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."
