Video memory: Another spec to consider is VRAM—a graphics processor’s dedicated video memory. The GTX 1060 and GTX 1060 Max-Q both come in two versions: one with 3 GB of VRAM, the other with 6 GB. (The GTX 1050 Ti appears to have only one version with 4 GB.) How much VRAM you need depends on the resolution you’re using (1080p in this case), the games you play, and the settings you play them at. Most games don’t need more than 4 GB of VRAM at 1080p, but some games do—and the list has doubtless grown since this 2015 TweakTown article published. Since the lower-VRAM options don’t often cost less, we focused on laptops with 4 GB or 6 GB of VRAM; they’ll play more games at higher settings for longer.
When it comes to GPUs, NVIDIA’s GeForce GTX 10-series have made it possible for manufacturers to trim down the overall size of gaming laptops without sacrificing features like battery life, making them powerful and portable. AMD's also basically non-existent in the mobile space these days too, so if you're shopping for a cheap gaming laptop you're probably getting one with an Nvidia GPU under the hood.
The E 15 offers a max resolution of  1920×1080, although this will need to be set to 1366 x 768 to retain a frame rate of over 30fps when playing more demanding games. The NVIDIA GeForce 940MX offers slightly better performance than a 940M card and, unlike some of its competitors, the Aspire E 15 E5-575G-57D4 features faster GDDR5 video memory instead of GDDR3. Acer have also fitted the Aspire E 15 E5-575G-57D4 with the latest generation Intel Core i5-7200U processor, which is powerful enough to handle more hardware intensive apps and games.
Gaming laptops can put a serious dent in your wallet, with some of the fancier models costing upward of $3,000. But who says that the right rig has to cost an arm, a leg and the soul of your firstborn? Fortunately for the fiscally conscious gamer, there are some sub-$1,000 notebooks that can run graphically taxing games like Destiny 2 and Shadow of the Tomb Raider at solid frame rates.
