The Acer Predator Helios 300 offers a balance of performance and value, suitable for gaming and general use with a capable GPU and a high refresh rate screen, though it's less portable due to its weight and battery life. In contrast, the Lenovo Legion Pro 7i (2024) is a powerhouse with top-tier performance for gaming, 3D rendering, and machine learning, thanks to its advanced GPU and CPU. It also boasts a higher resolution screen with better color accuracy and a faster refresh rate, making it ideal for engineering tasks and intensive gaming. However, it comes at a premium price and is bulkier, which may impact its portability. If budget is a concern and you prioritize general use with some gaming capability, the Acer is a solid choice. But if you need cutting-edge performance and are willing to pay for it, the Lenovo is the way to go, especially for demanding applications and professional use. Give Feedback

Christian Hintze | November 2022
"The Acer Predator Helios 300 review is an overclocked gaming laptop with a good display. The Predator is large, heavy, and loud, but also offers plenty of performance according to gamers. An overclocked gaming laptop - or its user - also has to struggle with the usual disadvantages we mentioned above. On the other hand, overclocking is optional, and those who like it quieter and can live with a few less frames per second can also switch to the significantly more moderate Standard mode. Then the Helios 300 won't be any louder than the competitors."

"Passionate gamers who want to play demanding modern titles with maximum details and don't mind spending the moolah will find the Lenovo Legion 7 Pro to be the right choice. The bright, sharp, and color-accurate 16:10 QHD 240 Hz display makes for an immersive viewing experience. The hardware is housed in a stylish chassis that feels premium and scores well in terms of workmanship and stability. Other aspects such as sound quality, input devices, and connectivity also seem to be near-perfect."
