Few companies have laptop barebones and selection is almost none for ones with capable gpus. I know MSI has a barebone version of their gaming laptop but you won't find it on sale so it's not cost-effective.
Good deals include Asus g73 with 2630qm, 460m, 1080p display. Newegg sold out of it recently for <$800 after rebate. Otherwise, xoticpc has some good deals on 15" laptops with 2630qm, 540m, 1080p/900p for <$900 that are actually regular sized (<6lb).
If you want max eyecandy, you're much better off building a $700-800 capable desktop than a >$1500 laptop that will struggle to match a $600 desktop's performance.
