Dell has updated their XPS line with the M1730, now available with two of the fastest mobile graphics chips. It has a Core 2 Extreme X9000 mobile CPU running at 2.8GHz, a pair of GeForce 8800M GTX cards in SLI, and two 200GB 7200 RPM drives in RAID 0 configuration. The XPS M1730 is said to be the “fastest mobile CPU on the market”. Unfortunately the price is about $4,500 but it should be worth it.
