Yes sir, I got one of them (G74SX-3DE).
Aside from the 3D, I think the only other difference with the G74SX-A1 is the matte screen (I love it- doesn't strain the eyes and the color-vibrancy).
I've had it for a month now and it's been running as it should be, except for one thing.
There was a bright dot on the screen. I remedied it by turning the screen off, then applying pressure to its exact location with the tip of a pen.
Then I turned on the screen again, and the bright dot was aligned back (problem solved:)).
I changed the stock 7200 rpm primary disk into a Crucial M4 128 GB SSD, did a clean install of Win7 Ultimate 64, installed win7 SP1 and other updates, and the necessary ASUS drivers.
Right away, I noticed the difference was significant. My boot time with the SSD is around 20 seconds. Same goes with gaming, file reading and copying, and the like. Everything seems to be working faster than with the stock HDD.
One of the reasons I chose the 3D version is that I wanted to watch movies and play some games in 3D with it. And this baby-beast didn't disappoint. Simply awesome. Since my wife loves it, too, now I need to buy another pair of Nvidia glasses just so we can watch movies together..
Been reading on this Forum about hardware and software issues (and there are a lot of them). But I'm glad that until now, I didn't have any trouble with mine. Guess I'm one of the lucky majority:)
I saw at Gentech PC (where I bought mine) that the G74SX-3DE is now Asus G74SX-DH73-3D, and the i7-2630QM is now upgraded to i7-2670QM. The good news for would-be buyers is the price is still the same!.. (Am I now having a tinge of buyer's remorse?.. should have waited a bit longer..:()
Bottom line, methinks it's really up to you which one to choose. For me, I like the 3D version so I went for it, even if I need to pay a bit more.
Good luck.
