Dell is selling a $10K XPS 600 system which starts at $9,930 and comes with a 30-inch LCD monitor and quad-SLI graphics.

The XPS 600 Renegade comes in a custom-painted case inside which sit four GeForce 7900 GPUs each with 512MB of video memory ready to run games at 2,560 x 1,600. The unit also features an Ageia PhysX processor on which games can offload all their complex physics calculations to free up the CPU - a dual-core Pentium D Extreme Edition "factory overclocked" to 4.26GHz, no less - for stuff like artificial intelligence work.

Dell's also put a SoundBlaster X-Fi Fatal1ty sound card in the box, which also houses a Western Digital 160GB, 10,000rpm Raptor hard drive and - in case you run out of room - a second WD HDD, a 400GB, 7,200rpm job. There's 2GB of dual-channel 667MHz DDR 2 connected to the CPU via an Nvidia nForce 4 SLI chipset.

All this, plus the 30in 3007WFP monitor, comes to $9,930, but Dell said it has a range of lesser spec'd machines for gamers on a tighter budget. It also said it was offering the Ageia physics controller on its regular XPS 600 and XPS 400 desktops in versions priced at $2,039 and $1,239, respectively.
