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.
With that said, everything about the Razer DeathAdder Chroma is new and improve, making it one of the most impressive gaming mice to step in the gaming industry; in case you are wondering what your money gets you basically get an amazing optical sensor that is capable of delivering an output of 10,000 DPI, and yes, you can control the DPI as per your liking, so even if you want to go lower, you can easily do so.
Last but not least, if you're a professional gamer looking to buy a gaming laptop that can keep you competitive, be prepared to brown-bag your lunches for a while. That kind of high-end performance can only come from top-of-the-line components, especially in a portable package, and they don't come cheap. Plus, an emerging trend among high-end machines is a high-refresh-rate screen built into the laptop, which allows for display of lofty frame rates in full to smooth out the perceived gameplay. Note, though, that you'll need a powerful graphics chip to leverage the benefits of a high-refresh panel with demanding games. You'll be able to identify machines like these by marketing lingo touting, say, a 120Hz or 144Hz screen. (A typical display on a laptop is a 60Hz panel.)
However, I found that that the Rival 500's generous controls may also contribute to its biggest problem: a lack of weight. As with other mice with 10+ buttons, there's just not much heft to the body of the mouse itself. With no option to add more weights, the mouse feels feather-light, and not in a good way. This isn't a huge issue, especially if you like lightweight mice, but it's the cost of essentially having a keyboard in your right hand.
For a high-end system, we recommend 16GB, so you can have more than one gaming session, your messaging app, several websites, a webcam program, and your video streaming program open simultaneously. A midrange gaming laptop should function fine with 8GB of memory, but be aware that many new laptops are not upgradable. You may be stuck with the amount of memory you order.
You'll want to make sure you get the most graphics power you can afford from the start since this can't be upgraded later, unlike memory or storage. If you're on a strict budget, go with one of Nvidia's Geforce GTX 1050 or 1050Ti graphics cards, which will give you good performance on newer games at medium or high settings with prices starting down around $600. If you can afford to spend closer to $1,000, you'll be better off in the long run getting a laptop with an Nvidia GeForce GTX 1060 Max Q with 6GB of memory.

Let's take a look under the hood: The new ASUS Metal is an amazing choice for gaming. It runs all PC games we threw at it flawlessly at medium settings. The laptop is powered by Intel's 6th-generation Core i7-6500U. Of course, you can tune the CPU from 2.5GHz up to 3.1GHz with Intel's TurboBoost for even more performance. The laptop's GPU is a NVIDIA GeForce GTX 960M. There's a good reason why most budget gaming laptops include this card: It offers a great price-to-performance balance and very long lifespan. The laptop's specs are topped off with 8GB of RAM and a generous 512GB SSD storage. It's a solid combination that runs games well.

For proper functioning of GPU, it is essential to have VRAM of their own. This is beneficial in storing different frames, textures and other required properties for getting frames for the monitor. Finding out how much you require may be tricky. Hence, it is better to go for a laptop with as much VRAM as possible. You can buy a laptop with 3-4 VRAM. If you have reduced budget, you can opt for 2 GB VRAM. You, however, need to ensure that the resolution of the gaming laptop is 1080P.
$3,000 or more: This is where things get crazy. With this kind of budget you can get a high-res display, custom paint job, up to four SSDs in RAID configuration and a maximum of 64GB of RAM from manufacturers like OriginPC and Maingear. Depending on the notebook, you can get two 1080 GPUs in SLI configuration with each card sporting 8GB of VRAM.
