Tom's Hardware
Brandon Hill | February 2023
"The Gigabyte Aorus 15X is a strong showing of Raptor Lake and RTX 4000 series. While the Aorus had trouble keeping up in older games like Grand Theft Auto V, it nudged past the competition in Shadow of the Tomb Raider. It also flexed its next-generation muscle in Far Cry 6 and Borderlands 3. While we were impressed with the overall build quality and design of the Aorus 15X, the keyboard lacked good tactile feedback. The display performed well in real-world testing despite its on-paper shortcoming with brightness, but the speakers are lackluster at best."

PCMag
Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
