I think the Asus G51JX (option 3 from TigerDirect) is the best gaming laptop.
Core i7-920QM, 1920x1080 res on a 15.6" screen, 4 GB of DDR 1066 and the GTS360M.
Of course, the GPU isn't as good as the GTX260M in the recertified Asus G71 from Newegg (option 2) but I think the Core i7 beats the Core 2 Duo enough. Plus, the G51 has higher resolution despite the smaller screen.
Reason I don't choose the Toshiba is because 18.4" is way too heavy. 9.70 pounds vs 7.26 of the Asus G51. I know 2 pounds doesn't seem like much, but you'll feel it when you're hauling it around.
