Dell has upgraded its Precision family of mobile workstations, adding a pair of new models to the line-up, both equipped with mobile-oriented Nvidia Quadro FX GPUs and Intel dual-core microprocessors.

The Precision M90 and M65 both use Intel's 945PM chipset and ship with up to 4GB of 667MHz DDR 2 SDRAM. Dell is offering the machines with Core Duo CPUs ranging from the T2300 to the T2600, and up to 120GB of 7,200rpm Serial ATA hard disk storage.

The higher-end model sports a 17in display driven by a Quadro FX 2500M graphics engine with 512MB of dedicated video memory or an 1500M with 256MB of memory. Screens are offered with native resolutions of 1,440 x 900 or 1,920 x 1,200.

The M65's 15.4in display is connected to a Quadro FX Go 350M with 256MB of memory. Dell is offering native resolution options of 1,680 x 1,050, 1,920 x 1,200 and 1,280 x 800.

Both machines ship with a Trusted Platform Module security chip ready to work with the integrated smart-card reader - which ships as standard - and an optional fingerprint scanner. They also include 802.11a/b/g Wi-Fi.

Prices start at £1,099 for the M90 and £949 for the M65. Prices exclude VAT and delivery, Dell said. ®
