MSI GS66 Stealth review: A 300Hz gaming laptop in a crowded field


The GS66 is a solid follow-up to MSI's groundbreaking GS65 Stealth Thin. It's more powerful in every way, it has a blazing fast 300Hz screen and it even has a decent keyboard and touchpad. But it's heavier than before, and it doesn't stand out nearly...

Powerful hardware ; Slim and sturdy case ; Excellent 300Hz screen ; Great keyboard and trackpad

Heavier than before ; Expensive compared to some competition

MSI’s GS66 Stealth almost has what it takes to beat Razer


An excellent gaming laptop in terms of power and features, but it has a few strikes against it

Improved design ; Efficient cooling ; Powerful ; Big trackpad

Keyboard layout needs work ; The aluminum chassis flexes on the bottom ; Lots of bloatware ; Missing an SD card slot

The MSI GS66 Stealth is a powerful gaming laptop that puts forward the best design seen yet from the company. Speaking of design, it’s going straight after Razer’s Blade, and while it comes close, it whiffs on a few big details.

MSI's GS66 Stealth Gaming Laptop Packs Big Specs and Thankfully Goes Light on the RGB


There's always something I've appreciated about powerful gadgets that are able to hide their power levels. I'm talking about stuff like the Volkswagen Phaeton W12 that had essentially the same engine you got in a flashy Bentley Continental (minus a...

Clean, understated design, per key RGB lighting, beefier graphics, lots of ports, 300Hz screen

Gaming laptops that don't break your back or the bank are having a moment right now. To compete, the MSI GS66 Stealth will need to knock it out of the park.

Sleek all-black design;Stunning high refresh rate display;Strong gaming performance;Surprisingly long productivity battery life

A smudge magnet;Annoying plastic-y accents;No G-Sync

MSI GS66 Stealth Review: Hot Stuff - UNBOX PH


Verdict: MSI's GS66 Stealth is thin, light, and incredibly powerful but suffers from high heat when gaming. If you want a low-profile gaming notebook, have enough cash to spare, and don't mind loud fans then you might want to give the MSI GS66 Stealth...

Powerful hardware ; Sleek, metal chassis ; Fast, responsive screen

Not-so-great audio ; Loud fans ; Thermal performance is not great

MSI GS66 Stealth Review: Low Profile, High Temperatures


The MSI GS66 Stealth packs good looks, but it gets a little warm.

Attractive, sleek design ; Strong gaming performance ; 99.9 WHr battery

Runs hot ; Middling productivity performance ; Very loud fans ; Odd function key placement

The MSI GS66 Stealth has the looks of a flagship with strong gaming performance, but it runs hot and loud with so-so productivity power.

MSI Stealth GS66 15.6" Gaming Laptop - Intel® Core™ i7, RTX 2060, 512 GB SSD


Beautiful and colourful high refresh rate display. Neat design and slim form factor. Good thermal performance. Lightly lid RGB keyboard with variety of modes.

Display is dimmer for outside use. Too many pre-installed software that had stability issues. The biggest battery placed on laptop, yet cannot achieve the target battery life. The chassis picks fingerprints and smudges very easily. Some of the fit and...
