"What is left to say about the GeForce GTX 580M? Yes, this graphic card is without a doubt the new king of performance, and, yes, thanks to its various features and the better picture quality, the graphic card can distinguish itself from its main AMD competition."
"Take the most powerful NVIDIA GPU on the market. Now take another. That's what Alienware put inside our M18x: two GeForce GTX 580Ms, each with 2GB of video memory. What that translates to is the highest gaming scores we've seen from a laptop."
"How does the GTX 580M version impact our conclusions?
Well firstly our request for a faster GPU to assist those who want to try 3D Vision with maximum performance has been answered. The GTX 580M will allow gamers to play with far higher detail level and less compromises in stereoscopic 3D than the GTX 460M would and that alone could be a killer feature.
Speaking of compromises, the GTX 580M based M17x R3 is a machine where we rarely have to make them. In all of the key titles from the past year we are able to game at 1920x1080 and other than The Witcher 2, which makes desktop GPUs struggle; we are able to play with maximum in game detail. There were also a couple of occasions where we were able to add anti-aliasing too, DiRT 3 being a particular highlight with its smooth framerates using Ultra (DX11) detail and 2x anti-aliasing.
The M17x R3 is a very impressive system which excels on build quality and design. The addition of NVIDIA's GTX 580M to the configuration options makes it a phenomenal mobile gaming system too, allowing us to game at 1920x1080 with maximum image quality settings in the latest titles."
"The Origin EON17-S is a powerful, highly customizable gaming laptop that offers great performance and can even include overclocked components. "
"Our review unit had an overclocked GeForce GTX 580M, a $588 upgrade."
"PC games that require this kind of power are few and far between (The Witcher 2 is the most recent system-crushing example we can think of), but for serious PC gamers, it's nice to have that kind of headroom to play with, especially with high-profile games such as Skyrim and Battlefield 3 right around the corner.
