"the (Acer Aspire) AS3830TG stood out by including an NVIDIA GeForce GT 540M graphics chip. Its 3DMark 06 (9,255) and Lost Planet 2 (38.9 frames per second) scores were indicative of a portable gaming laptop and blew past the integrated solutions found in the R835-P50X and ThinkPad X1. It also leverages NVIDIA's Optimus graphics switching technology, which had a huge impact on battery life."
"And thanks to Optimus technology, the U46SV can switch between its discrete graphics card and Intel's integrated graphics to extend battery life to nearly 7 hours."
"The Alienware M11x's NVIDIA GT 540M graphics chip, which automatically switches back and forth with Intel integrated graphics by virtue of NVIDIA's Optimus technology, provides enough punch to play demanding games."
"[The Aspire TimelineX 3830TG] has NVIDIA's Optimus technology to switch between its integrated Intel HD graphics and the more-robust GeForce GT 540M discrete GPU on the fly. The laptop notched a high 3DMark06 score of 8,084, more than double what notebooks this size tend to muster (3,722)."
"Thanks to its Nvidia GeForce GT 540M discrete graphics chip, the Aspire TimelineX 5830TG-6614 has enough oomph to play demanding games at brisk frame rates."

"[An] integral part of the equation is the NVIDIA GeForce GT 540M graphics processor (GPU), which comes with 1GB of dedicated video RAM. You need to push a lot of pixels to draw 1080p scenes in such rapid succession, and the GT 540M is up to the task."

"While the GT 540M is not the fastest GPU in NVIDIA’s stable, it delivers plenty of graphics horsepower for those who want to mix gaming into their entertainment repertoire."

"Given that this is a resolutely gaming-focused machine, graphics oomph is what really sets this machine apart, though. In our gaming and graphics tests, the NVIDIA GeForce GT 540M chip in the M11x R3 provided a significant boost over the GeForce GT 335M in the M11x R2. We started these tests with Company of Heroes, an older game, and ran our DirectX 10-based workout with it; the M11x R3 gave us an impressive 42.4 frames per second (fps) running at its native resolution (1,366x768). The M11x R2, in contrast, only managed 28.6fps.."

"We have to give the Alienware M11x R3 props for one area in which it unequivocally excelled: battery life."

"faster graphics, and excellent battery life finally make the M11x R3 the true gaming ultraportable the line was meant to be. Gamers on the go will be smitten."
