How many years ago? Personal use tops reviews, but you must keep in mind how quick technology moves. Even the Precision M4600 isn't that loud, and it really gets going.
I mainly ask because what you're saying is the dead opposite of a review for the notebook in question.
About 3 or 4 years ago...
... and yeah I read reviews too back then... and I have come to the conclusion that most reviewers and especially Sager fanboys must be very much deaf.
Now I don't know what they changed in the last years... but their systems do not look all that radically different... and the components they use simply get way too hot for such a design to handle in general.
So.... my guess is you will either get a true jet turbine or something that overheats and has stability/throttling issues. The 580GTX with that CPU in the build linked above there is pretty much a guarrantee for that.
Also worth noting is that the Clevo barebones they use are on the very lowend of build quality. (or that was what my impression was anyways.)
(Compared to an actual business class notebook or even any regular notebook from a quality brand they are an utter joke.)
So what you'll be getting is a chunk of high grade PC components in a badly designed plastic case that is about as durable as an eggshell and absolutely unsuited for dealing with all the heat that those components produce in any kind of "sensible" manner.
Heck... even a crappy Dell/Alienware would be a step up from THAT. LOL.
And while I am definitely not a friend of Asus laptops (ugh build quality)... at least they took the cooling problem seriously (which is why their laptops look so fat at the back.)
Finally... why get such a "laptop" at all? It has pretty much zero portability. Battery life is nonexistant in these things and the one I had couldn't even use the GPU at full power in 3dmode at all, unless it was plugged in - so you are tied to the power grid and the wheight of those monstrosities is hilarious as well.
A small desktop with a carry case/bag propably isn't really all that much less portable
lol.
In any case.... my advice would be to get a desktop if portability is not an issue... and a well designed 13-15 inch laptop from a quality brand with hardware that will also be "ok" to play "most" games on, although not all of them at max settings, if portability is required. Trying to have it both ways with those socalled "gaming laptop abominations" is only asking for grief.
Besides... as said before for the 3800 bucks that this monstrosity costs, you actually can easily get both, a beefy desktop that can easily handle any game and a well designed laptop that can not only handle most games but is also portable. Depending on the specific desktop and notebook you buy, you would even have money left... and have higher quality computers lol.
