Sascha Mölck | July 2022
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
