Christian Hintze | January 2023
"Overall, the all-AMD system in the Alienware m17 R5 is impressive, especially the graphics performance. However, various driver issues and unnecessary inconsistencies prevent us from truly enjoying such a potent gaming machine. In addition to strong 3D performance, we particularly like the build quality, the fairly bright UHD display with high color space coverage, and the fact that the gamer is often quiet when not under load and also rather quieter than some competitors under load."

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."
