Windows 7 is upon us, and with the launch of Microsoft's self-proclaimed "best operating system" comes a slew of new desktop machines, notebooks, and netbooks looking to take advantage of its added stability and features.

One of the companies that is looking to serve up a number of new Win7-based rigs is Asus, and without a doubt they have assembled an interesting and compelling offering in their G51J-A1 notebook. Hitting the sweet spot between the average-sized 15" machine and the full-on desktop replacement, the refreshed G51 maintains the 15" form factor yet packs enough horsepower, with it's Core i7 mobile CPU and GeForce GTX 260M GPU under the hood, to plow through even the latest game titles.
