You can take a look at the Dell E1705. Dual processor cores available, true graphics device available, 17" screen, available with 7200 rpm drives, and the sucker weighs in at 8 pounds. I haven't seen or tried one myself. I'll wait till these get much lighter (with a smaller screen of course.)
Starting price is $999 with a single core processor, in a decent configuration (1G memory, 60G 5400 rpm sata hard drive, cdrw/dvd-rom combo drive), but I would update to the better display for $119.
If you pick the second configuration, it comes with a dual core processor in a decent config starting at $1127, and also includes a free dvd burner upgrade. Also, I would at least update to the higher rez display for $119. Also worth considering is the $80 processor speed bump upgrade.
Check with Consumer Report before you spend megabucks on a laptop. We did and went with a Toshiba for my daughter when she went to college last fall. She loves it!!
Also shop around as the price varies even for the exact same laptop.
