Without more overclocking, there is a noticeable distinction in notebooks, mainly because Kaby Lake models have clock of a few hundred MHz more than their Skylake equivalent. Although, for a price- performance causes, we don’t think you have mistaken with taking an older notebook. The GPU is the main factor in most of the games, and even the Core i7-6700HQ is more than enough for the coming few years.
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.
It is in the graphics department that this RoG Strix laptop has the upper hand, as it comes with a GPU none other than the GTX 1070, a high-end beast that masters 1080p gaming and can handle 1440p more than competently. Sadly, though, the laptop doesn’t come with a 1440p display, as the 17-inch screen really could have looked really good with such a high resolution. Nonetheless, the 144 Hz refresh rate is still here, so nobody will be left wanting when it comes to performance.
"Love it!...Good Mouse...I'm sure the mouse is built quite well, but my Logitech MX Anywhere 2 (a portable laptop mouse) feels more solid than the G305....The up to 12,000 dpi sensor technology in the G series optical mice is impressive, and honestly I would recommend anyone who spends a decent amount of time in spreadsheets or especially diagramming using a mouse purchase a gaming mouse for those uses as well - the high quality sensors make those jobs much easier."
For example, the Aero 15X, weighs just over 2 Kg and incorporates a GeForce GTX 1070 Max-Q graphics chip. Its keyboard is equipped with RGB backlighting and an anti-ghosting system. The Aero 15X also features two internal M.2 NVMe format connectors. Let’s not forget that it is also equipped with a 15.6-inch Full HD display operating at a frequency of up to 144 Hz (which is also factory calibrated). Other models are equipped with a QHD display (Aero 14K).
Alienware laptops are known for their cool designs and high-end specifications which deliver a superior gaming experience. It features an Intel Core i7 7th Gen processor and 8 GB of RAM, along with a 6 GB NVIDIA GeForce GTX 1060 graphics card which runs almost all the advanced games seamlessly. Its 1 TB HDD and 256 GB SDD provides ample space to store your pictures, videos and music.
Under $1,000: While you might see a few notebooks with Intel Core i5 processors at this price range, there are plenty with 7th-generation Intel Core i7 CPUs and at least 8GB of RAM. Display-wise you can expect a 1080p display with average color reproduction, accuracy and brightness. Now that SSDs are becoming more commonplace, you can get a solid SSD at below $1,000. However, it's unlikely that it'll be a slower configuration instead of a high-speed PCIe device. Your rig will probably be outfitted with 1TB HDD (usually 5,400-rpm) and a Nvidia GeForce 1050 or 1050 Ti GPU with between 2-4 GB of VRAM. A laptop with these specs can play most titles at a solid frame rate at medium settings, but you can expect some trouble at higher configurations. (See our favorite sub-$1,000 gaming laptops here.)
