    • Big Screen, Big Power, No Regrets: MSI Stealth 18 Thank you
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
I’ve been spending time with the MSI Stealth 18 HX AI, and honestly, it’s a monster of a laptop — in both power and size. The first thing that hit me was the screen. That 18-inch QHD+ panel at 240 Hz is just beautiful. Games look ridiculously sharp and fluid, but even outside of gaming — browsing, or just having multiple windows open. Its massive but yet portable if that makes sense. Performance-wise, it’s exactly what I expected from an Intel Ultra 9 275HX paired with an RTX 5080. Everything flies. I’ve thrown heavy games at it no stutter, no lag. Even with background stuff running, it never slows down. Laptop get warm but not hot, and the fans can definitely be heard when the GPU kicks in, but that’s the trade-off for this kind of laptop. I like that the design doesn’t scream “gamer.” The chassis looks sleek, almost professional. I’ve taken it into meetings/coffee shops without feeling out of place, and people usually don’t realize it’s a high-end gaming laptop. The downside — it’s big. Make sure you get a backpack that can fit at 18in laptop. I mainly use it docked at home, connected to a monitor and keyboard, but it’s nice knowing I can unplug and still have full desktop-level power if I need to. Battery life is what you’d expect: “OK”. I get maybe a couple of hours doing light work (4 to 5 hour, and much less if I’m gaming. Storage and memory are solid — 32 GB DDR5 and 2 TB NVMe give me more than enough space and speed Overall, this feels like the kind of laptop built for people who want it all and don’t mind the size or power draw. It’s overkill for casual users, but if you game seriously, create content, or just like having absurdly strong hardware, the Stealth 18 HX AI absolutely delivers. ... show more

    • Good upgrade,no complaints.
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
My previous laptop was a gateway nv79 so this was a definite upgrade. So far only issue I've had is finding a decent bag/hardcase the visuals are awesome,sharp images when watching online content. Switched up the background wallpaper,wasn't feeling it. Happy with purchase.

    • This thing is a Monster for gaming!
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
My Three Cents: Man, my cousin is a huge gamer and saved up forever for a new laptop. He wanted something completely nuts that could just destroy any game. He was looking at this MSI Stealth 18 and the specs are just... insane. It's got that new Ultra 9 chip and an RTX 5080, which is basically the best you can get. Plus 32 gigs of ram and 2TB of storage. He was so pumped when he ordered it, I was like "dude for that much money it better make you breakfast" lol. So he's had it for a week and he's obsessed. First off, the 18-inch screen is massive, and he says the 240Hz makes everything look like butter. He's running all the newest games on totaly maxed-out settings and getting crazy high FPS, no lag at all. He's also super stoked about the 2TB drive, says he can finally have all his games installed at the same time and not have to delete stuff. He said the light-up keyboard is sick too. Honestly this thing is probly stronger than my desktop. He wont stop texting me about how fast it is. If you got the cash and want a total monster laptop for gaming, this is 100% the one. ... show more

    • Can't actually put it on your lap, even to just watch a video.
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
They advertise this as having a 4k display but it actually only has a 2k display. You can get a laptop with an actual 4k display for not much more. The audio is also terrible with a Samsung Galaxy 10S tablet sounding better with more bass than this laptop that costs several times more! The legs on the bottom of the laptop are triangle shaped so they dig into your leg and create deep red and purple indentations. And the metal plate on the bottom gets so hot it turns you leg red! And that is just from watching videos! I had to put an aggressive fan profile on it to try and keep it from burning me. ... show more

CPU: Ultra 9-275HX RAM Size: 64 GB Hard Disk Size: 2 TB Graphics Description: RTX 5070Ti Style: 18" 240Hz QHD+
Solid hardware. Exceptional performance when gaming. I'd like to note the performance with path tracing on with a 4k modded Cyberpunk 2077 is a great benchmark. FPS was averaging 72 to 98 depending on DLSS

    • An absolute beast of a Laptop.
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
Very very good quality laptop. Compared to my slightly older one the MSI stealth 18 HX AI blows it out of the water. It is better at everything without compromising anything.
