If I was buying a gaming laptop I would buy one with a great screen and a fast CPU with an integrated GPU. Then buy one of those separate External Graphics Card Docks. You can put whatever GPU you wanted in there and could readily update your GPU. This would give you a great laptop for everyday use and when you thought you needed to game somewhere you could bring the External Graphics Card Dock.
There are also advanced features you won't find in a regular mouse. Look for additional buttons that can be programmed for specific PC games. Many gaming mice — both optical and laser — offer multiple DPI (dots per inch) settings to control the sensitivity, and some of them even allow you to adjust the DPI on the fly, so you can switch between settings without pausing your gameplay. And not only are these models the coolest mice when it comes to their standard look, a growing number of gaming mice boast RGB lighting for customizable effects in millions of colors.
With a comfortable shape, textured grips and 11 big, programmable buttons in a convenient layout, the Logitech G502 Proteus Spectrum (an updated version of the excellent G502 Proteus Core) has a great feel and stellar performance, and is the best overall gaming mouse on the market today. The device isn't specialized for any one genre, but it handles FPS, RTS, MMO or anything in between with grace and aplomb. Users can adjust the Proteus Spectrum's weight and set its scroll wheel to feel either resistant or almost frictionless. The Logitech Gaming Software can even scan your computer for games, automatically create profiles to fit them and customize the mouse's illumination with full RGB backlighting.
While it features a superfast solid state drive, storage space is slightly too small for modern games which can take up over 40GB of storage space once installed. You might want to consider upgrading the size of your SSD or purchasing a 7200rpm external hard drive for more storage space. We are also impressed with the Full-HD display which offers good image quality and vivid colors for gaming or streaming your favorite series. Acer claims that the Aspire E 15 E5-575G-57D4 will give you 12 hours of battery life off of a single charge, however this would be under ideal conditions and not while gaming or while using hardware intensive applications. Despite this fact, we are still very impressed with the battery life that it offers as most laptops in this price range will barely offer you 4 hours of run time.
