I just upgraded an older Z170 chipset P870DM3 (which Sager calls the 9873) with 9900K. +100% CPU power upgrade over 6700K. Ran a bench at 4.9ghz allcore this morning. Others have demonstrated the current Z370 P870TM model with >5ghz 9900K. (This same model was DAILYING 8700K at 5Ghz for 6 months before laptop coffeelake came along and boy it was a huge deal when ONE or TWO of the BGA i9's completed a short bench at 5ghz!). Utter beastly pieces of engineering, that make everything BGA else look puny by comparison. For sure they suck at portability, but if you don't place such a high importance on that, and you're talking best performance, this is it
The Dell G7 had the loudest fans of the budget gaming laptops we tested (except for the nearly identical Dell G5), and their whooshing drowned out in-game dialogue, forcing me to crank up the volume or put on headphones to hear. But the fan noise was an issue only when I was playing games—the G7 was dead silent when I used it for a full day of work—so it shouldn’t be a problem while you’re taking notes during class or browsing the Web.
Best Portability (13 - 14 inches): If you're constantly on the move, you'll want to consider 13 or 14-inch laptops like the Razer Blade. Notebooks in this size range typically weigh under 5 pounds and tend to have longer battery lives with an average endurance of 7 hours and 38 minutes. However, 13 and 14-inch gaming laptops usually don't come with the most powerful CPU or GPU, because they just don't have enough space to dissipate all that heat.
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.
Why a laptop right now? With both desktop graphics card and RAM prices still inflated well over MSRP, the notebook space has never looked more attractive. A year or two ago, the price gap between desktops and laptops with comparable performance was significant. That's changing, and now we're paying an almost insignificant convenience tax to have desktop performance in a portable form.
The Acer Predator Helios 300 has Nvidia GeForce GTX 1060 graphics and a 144 Hz high-refresh-rate display, but its WASD keys reached 110.2 °F, the hottest of any budget gaming laptop we tested this year, even with Acer’s Cooler Boost software enabled. Its fans sounded high pitched and a bit grating, it had a poor 3.5-hour showing in our battery life tests, and it comes with too much bloatware.
More the issue is knowing how your mouse connects to its host. The three main possibilities are USB (via a typical cable), USB (wirelessly, via an RF USB dongle), or Bluetooth (also wireless, usually via the host's built-in Bluetooth radio). Bluetooth is the least common of the three in gaming mice; it tends to be found more often in productivity or mobile mice. Note that some wireless models with rechargeable batteries come with a USB charging cable that can double as a mouse cable while you're juicing back up, letting you continue using the mouse with the battery depleted.
Starting at $699, it's going to be hard to find a more affordable gaming laptop than the Asus TUF Gaming FX504. For the price, you get an 8th Gen Core i5 CPU and a Nvidia GTX 1050 GPU, which is enough to play most games on low or medium settings. Keep in mind that such a low price point, means that some sacrifices must be made. But if you want to spend as little money as possible for a gaming rig, the FX504 is the way to go.
