Andreas Osthoff | June 2023
"With the release of the TUF Gaming A15, Asos have concentrated on the essentials: gaming performance. Our base version, which can be had for around $1,169, already provided enough power to play current games smoothly in a native resolution of 1080p and with maximum details - thanks to its new Nvidia GeForce RTX 4050 Laptop. If you utilize upscaling, then you can even manage to run ray tracing."

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."
