Alienware is taking orders for Area-51 ALX gaming systems featuring NVIDIA SLI technology. The water-cooled systems are decked out with dual GeForce 6800 Ultra graphics cards, but saddled with Nocona-core Xeon processors. With an estimated shipping date of December 1, ALX systems could be the first commercially-available NVIDIA SLI platforms. However, with nForce4 SLI on the way and the Athlon 64 trashing the Pentium 4 in games, more appropriate and affordable SLI platforms may be available before long.
