As far as the gaming performance of this laptop is concerned, the HP 15-ay191ms comes with the 7th Generation Intel Core i3 processor paired with the 8GB of RAM and 1TB of hard drive for storage. Thanks to the integrated Intel HD graphics this laptop can run some of the popular older games at low to medium graphics settings. Moreover, the audio on this laptop is powered by DTS Studio Sound which makes watching movies and gaming on this laptop more immersive.
That said, notebooks aren't upgradable, apart from their primary system memory (RAM, not to be confused with the graphics memory) and in some cases, the storage. You're going to be stuck with the screen, the graphics chip, and the processor you buy now, so evaluate these parts wisely. If you can stretch your budget a bit to get the next-tier-higher component, it can pay dividends in terms of usable life.

Nvidia Max-Q Design - Nvidia has teamed with laptop manufacturers to create Max-Q,  a new design specification which  focuses on efficiency rather than performance. Essentially downclocking Nvidia GPUs can place a powerful 1080 GPU into the 0.5-inch thick Asus ROG Zephyrus. With less power being consumed, the system is producing less heat, which means the fans aren't being used as much. That means you get a system that's cooler and quieter than your typical gaming laptop and nearly as powerful. Max-Q designed GPUs will include the 1060, 1070 and 1080 GPUs.
