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.
Even if you're not familiar with Logitech's standard gaming mouse filigree, the G502 is very intuitive. It features two center/top buttons, one for toggling the mouse wheel between "loose" and "granular" settings, and one for adjusting DPI presets on the fly. This is the case for most Logitech mice, but it's nice to get both options on such an affordable product, and one that also features multiple tunable buttons. The G502 also uses a handy LED-based DPI indicator for various settings—normal, fast, super-fast, and slow—so it's especially good for shooter scenarios where different weapons call for different optimal speeds.
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.
