I must say, the processing was quite simple. it was matter of waiting for the email to be send with Key & download link of the software.
Anyway, Since the G74SX comes with only the Trustudio THX along with THX EAX 5.0. you aren't really benefiting from the real sound. I still don't understand why ASUS did not offered us the software itself with the laptop, instead of giving us a very limited one.
Anyway, the Audio chip onboard of the G74SX is decent, along with it's CPU, compare to a REAL sound blaster card (comes with Creative hardware tweaks) there isn't much difference besides the Volume strength & The bass strength (compared to a Recon3D, it comes with Quad-core, see those Core actually pushes the Frequencies of EQ & bass quality, the rest is just software related and has nothing to do with the Hardware itself)
My reaction when i installed it, i saw the nice black/orange color, I was SOO excited (im a big audiophile)
as you can see, it comes with Trustudio PRO & Creative console launcher.
And also comes with widgets and 5.0 EAX
My conclusion, for 24 Bucks? HELL YEAH, its worth every penny. ESPECIALLY FOR the G74SX. you just get every inch of perfection on the laptop. Since i upgrade my ram, SSD and now somewhat My sound card. I really feel like this laptop could of came with all of these on the first go, but hey i'm happy ;D
I recommend strongly, i'd give the software FOR the g74sx a 8/10. Compared to a Recon3D i had on my alienware. the only difference is you aren't getting that Voice FX (just changes ur voice) & the big strong bass booster from EQ settings (due to it's 4 quad-core build in chip) but really, this software bass booster is strong enough, especially since i never thought the stock Onboard Realtek HD audio that came with the G74SX could still deliver strong sound quality. Also, blasting it loud, there is no more speaker noise, or bad distortion, was really happy ! and saying it again, with earbuds/headphones, the sound production is very nice ! dynamic and crystal clear.
Now the only downside i hate about the G74SX, are the speakers themselves, they are good don't get me wrong, but they just aren't very loud enough, but alas. Using vulcan headset & using my laptop speaker on a living room or 5-10 feet away, still feels very crisp and Loud enough if things aren't noisy around the area ( i'd say if you live in an apartment, open ur window and hearing traffic. you will still hear every sound coming up from speaker, just not very loud to bleed ur ears. but it's a laptop don't expect clubbing with it lmao
Also, i understand many people dislike the Trustudio that came pre-installed. i hated it too, but this my friends, This is just freaking amazing. Software can always make a huge change, not just Hardware itself.
Edit: This can support up to 5.1 Surround. Now im not sure about 7.1, but it should .
Updated: If you noticed, every new Models of 2013 laptops of every brands out there are putting stock Realtek sound card now. I don't know why
