ASUS'  newest powerhouse, the 17-inch G74SX-A2, looks like the kind of rig  that gamers' dreams are made of. It's equipped with a powerful quad-core  Intel Core i7 processor, 16GB of RAM, a discrete Nvidia GeForce  graphics chip with 3GB of RAM, and two hard drives, one of which is an  SSD. Still, when a laptop is priced north of $2,000, most gamers want to  make sure they are getting a quality machine that can handle  today's--and tomorrow's--most intensive games. So does the G74SX offer  the best bang for your gaming buck?
Design
With the  G74SX-A2, ASUS has once again drawn inspiration from a stealth vehicle.  But unlike the stealth fighter-inspired G73SW and G73Jh, the design of  the G74SX-A2 was inspired by the US Navy's Sea Shadow stealth ship,  which is evident in the system's sleek, sculpted angles and menacing  black color scheme. The lid of the G74SX-A2 is covered in a soft-touch  rubberized material that feels smooth, resists finger print smudes, and  provides an overall sense of quality. Below the inlaid silver ASUS logo  is ASUS' Republic of Gamers logo. Around back you'll find the G74SX-A2's  most defining feature, two oversize fan vents that span nearly the  entire width of the unit. Surrounded with chrome accents, the vents are  clearly made to stand out, and they certainly do.
The G74SX-A2 is  as sleek inside as it is outside. The deck is a dark-silver brushed  metal that helps to break up the notebook's overall black color scheme.  ASUS coated the G74SX's palm rest with the same rubberized material used  on the lid, giving it a soft, comfortable feel, something users will  undoubtedly appreciate during marathon gaming sessions.

At  the top of the deck are a speaker bar, power button and Power4Gear  Hybrid Key, which provides users with a shortcut to switch between  various power settings. On models equipped with a 3D display, the key  enables or disables the system's 3D functionality. Four pin-size status  lights (for battery life, Wi-Fi connection, hard drive, and keyboard  backlighting) are located at the bottom of the deck, but they are  difficult to see under even the dimmest lighting.
Weighing in at  10 pounds and measuring 16.6 x 12.8 x 2.3 inches, the G74SX-A2 is a  hefty machine, even for the desktop replacement category. Its dimensions  match up evenly with ASUS' previous gaming powerhouse, the G73SW (16.6 x  12.8 x 2.3 inches), but the G74SX-A2 is more than a pound heavier. The  system also dwarfs several of its competitors, including HP's dv7t (16.3 x 10.8 x 1.4 inches, 7 pounds), Dell's XPS 17 (16.3 x 10.5 x 1.5, 8.9 pounds), and even Alienware's M17x  (16 x 11.9 x 1.8 inches, 9.6 pounds). Carrying around the notebook  wasn't too much of a hassle, but you'll want to invest in an oversized  backpack if you plan on traveling with it.
Keyboard and Touchpad
The  first thing you'll notice about the G74SX-A2's keyboard and number pad  is that they are separated by a roughly 1-inch column of empty space, at  the bottom of which you'll find the system's directional keys. What's  nice about this design is that it gives the keyboard the feel of a  standard-desktop keyboard setup, and provides gamers with enough room to  use the directional buttons without accidentally hitting any nearby  keys. ASUS also increased the size of the Control and Shift keys on the  left side, making them easier to tap, which proves helpful when playing  fast-paced games that require quick and accurate key inputs.

Overall,  the G74SX-A2's keyboard was a big improvement over the previous  generation. The keys still don't offer much tactile feedback, but we  didn't have to be as deliberate with our keystrokes as last time around.  Structurally, the keyboard is solid, with only a small amount of flex.  When using the Ten Thumbs Typing Tutor, we averaged 63 words per minute  with a four-percent error rate. That's comparable to the 64 words per  minute and two-percent error rate we scored on a desktop keyboard.
The  G74SX-A2 also offers several hot keys, including the Splendid key,  which lets users toggle between different display color modes to improve  contrast, brightness, skin tone, and color saturation. The Power4Gear  Hybrid key lets users switch between different power settings ranging  from high performance and entertainment to quiet office and  battery-saving modes. Gamers will appreciate the touchpad toggle key,  which helps eliminate accidental input from the touchpad when using an  external mouse.
ASUS outfitted the G74SX-A2 with an enormous  touchpad. Measuring 4.1 x 2.5 inches, it's larger than the one found on  Alienware's M17x. We found scrolling to be smooth and accurate, and the  two buttons were soft and offered great feedback. Multitouch gesture  support includes two-finger scroll, pinch-to-zoom, and image rotation.
Heat
The  two massive air vents located on the back of the G74SX-A2 aren't just  for show. ASUS chose to vent heat out the back of the unit rather than  through the sides and back, as is typical of most laptops. This design  allows hot air to be blown away from the user. During our heat test,  which entails streaming a Hulu video for 15 minutes, temperatures  between the G and H keys reached no higher than 81 degrees, while the  palm rest area measured only 80 degrees. The underside of the system,  meanwhile, stayed a relatively chilly 78 degrees.
Display and Audio

The G74SX-A2's bright 17.3-inch, 1920 x 1080 display was top-notch. Trailers for 
Captain America and 
Cowboys & Aliens looked great, and a Blu-ray of 
The Sum of All Fears  was clear and crisp. Viewing angles for the display were decent, with  images only washing out slightly at 40 degrees. The Splendid key's  multiple display color modes (which include Correction, Gamma, Normal,  Theatre, and Vivid) proved quite useful when we watched a movie in a  darkened room. The screen's only drawback was its glossy finish, which  kicked back reflections under bright lights.
The G74SX-A2's Altec  Lansing speakers pumped out impressive sound, with enough power to fill a  small room. We found the system's audio quality to be spot-on while  listening to Radiohead's "OK Computer." That's in no small part thanks  to the the notebook's THX TruStudio software. The software offers three  different sound profiles for use with the G74SX-A2's built-in speakers,  external speakers, or stereo headphones. When TruStudio is turned off,  audio quality degraded drastically. Songs instantly went from sounding  full and rich to flat and tinny, which makes us question why you would  ever turn it off.
ASUS also includes Realtek's HD Audio Manager  for those users who want to really fine-tune the G74SX-A2's sound. We  did notice a difference in the speakers' audio quality as we changed the  software's settings from CD to studio quality, but the effect wasn't  nearly as dramatic as when we flipped through TruStudio's settings.
Ports and Webcam
The  G74SX-A2 comes with every port under the sun. On the right side are a  USB 3.0 port and USB 2.0 port, as well as Ethernet, HDMI, and VGA  connections. You'll also find a 5-in-1 media card reader. On the left  side of the rig are two more USB 2.0 ports, audio in/out ports, and a  Kensington Lock, as well as the system's Blu-ray drive.

This  notebook's 2-megapixel webcam offered crystal-clear images in both  brightly lit and darker rooms. When viewing a local image through Skype,  we couldn't see any pixels or shadowing around faces, and when we moved  to a position with a bright window behind us, the cam compensated for  the additional light. Curiously, ASUS does not ship the G74SX-A2 with  any webcam software for recording videos or adding special effects  during your video chats, but its Virtual Camera Utility lets you tweak  the camera's settings, such as sauration and brightness.
