"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."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
