Florian Glaser | February 2021
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."

Mark Knapp | July 2023
"It doesn't quite match its Legion Pro 7i sibling as an Editors' Choice winner, but Lenovo's AMD-powered Legion Pro 5 Gen 8 is a stylish, well-built gaming laptop with solid performance at both 1080p and its sharper native resolution. It's cheaper than some comparably equipped machines and better than some similarly priced ones. That's a recipe for success, even without its frequent availability of discounts or sales. A brighter screen and longer battery life would be nice, but even as is the Legion Pro 5 earns a solid recommendation."
