Dell has announced three new gaming machines that use the new Intel Core i7 CPU with Intel's X58 chipset. The three systems include the Alienware Area-51 X58, Alienware Area-51 ALX X-58 and the Dell XPS 730x. The two Alienware machines offer up to 12GB of triple channel DDR3 RAM while the XPs machine offers up to 6GB. The platform supports both SLI from NVIDIA and CrossfireX from ATI and supports RAID. Power supplies are available with up to 1200W in Alienware machines.

Performance increase using the new processors is over 20% compared to previous generation gaming platforms. Intel Core i7 processors help the rigs crank out maximum benchmarks at peak game settings. Other features of the machines include AlienFX lighting, Alienware Command Center advanced user controls, and the XPS machine has lighting inside the case that turns on when the side panel is removed. The Alienware systems can be air-cooled or optional AlienIce cooling is available.

“By incorporating the revolutionary capabilities of Intel Core i7 and Core i7 Extreme Edition processors into the Alienware and XPS lines of gaming systems, Dell Gaming continues to lead the industry in delivering performance levels and in-game benchmarks that shatter all previously perceived limitations,” says Arthur Lewis, head of Dell gaming group.
