Jumping right in, the G51Vx and G60Vx appear to share identical specifications, apart from the extra .4 of display on the G60. They each offer the choice between a host of Intel Core 2 Duos and a Core 2 Quad Q9000. They have an Intel PM45 + ICH9M chipset, up to 4GB of DDR2 800MHz RAM, an Nvidia GeForce GTX 260M with 1GB DDR3 VRAM, support for dual SATA HDDs (up to 1TB 5400RPM and 640GB 7200RPM), a Blu-ray combo drive and a 2 megapixel webcam.
Asus claims to have remedied the typical thermal issues presented when squeezing a GTX 260M into a 15 form factor. The laptops weigh in excess of 7lbs when equipped with a 6 cell battery and single HDD. Theres no word on US availability, but folks in the UK are looking at a September launch date and a price of £1,500 (about $2,475).
