    • Just what I was looking for
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
Im a truck driver. Was looking for something high end that was easier to take on the truck and back home. This thing delivers. It's thinner than other models with the same specs. After updates everything worked as intended. It is a a 1600 display and not 4k. The screen looks good. Lights are adjustable to how you want them. All my wireless things hooked up without issues. Now for the games. I play cyberpunk, Farcry games, elden ring, world of warcraft, and call of duty. All games play on the highest settings with good fps. It gets warm after awhile. It doesn't lift too far off a surface. I got a 50 dollar cooling pad to go with it and is perfect now. ... show more

    • 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

CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
After my 10 year old MSI laptop starting acting up, I knew I wanted another MSI. The MSI HX AI Gaming Laptop is primarily used as a desktop replacement. It runs Windows 11 Home. The laptop is fast and has good graphics display. I loaded MS Office 2024. The only problem I had was some that I had multiple virus softwares running at once. The only virus software I run now is Windows Defender. The laptop is perfect for my needs. ... show more

    • VR headset issues
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
Even though it’s a high end gaming laptop, with a high end rtx gpu, the two usb-c ports that have the thunderbolt and dp function are only wired to the integrated gpu. Thus making it impossible to run vr headsets from the more powerful gpu.

This is NOT a 4k laptop like it says in the description The resolution is 2560x1600 Some of the key caps are too translucent they are meant to highlight certain keys but are too bright compared to the other keys All the side usb c ports are on the left side Otherwise I like the laptop and will keep it though I wanted a 4k one sound is pretty good ... show more

    • I highly recommend
CPU: Ultra 9-275HX RAM Size: 32 GB Hard Disk Size: 2 TB Graphics Description: RTX 5080 Style: 18" 240Hz QHD+
So far, the performance has been fantastic! I upgraded from an omen 16, and since I play first-person shooter games, my FPS has increased significantly from 62 to 200 FPS. I highly recommend this upgrade, but please note that it’s not cheap.

    • 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
