Hey rick, (yes I know you lol)
I will take this thread as "I'm willing too buy a laptop, please tell me which one you recommend"

.
I have recently bought a HP pavilion dv7-6163cl for $830 (including tax) - with the following specs:
CPU: Intel Core i7-2670QM
RAM: 8GB
Screen: 17.3 inches (widescreen)
HDD: 450 GB
Weight: 7.4 lb (3.3 kg)
It also has 2 graphics cards so you can switch between them either manually (needs edit in BIOS settings) or automatically:
AMD Radeon HD 6770M
& Intel HD Graphics 3000
I'm not using FG anymore so I haven't tested it there yet, but it runs at 60-100 fps in X-plane (which also uses OpenGL) at medium settings. So it should work with FG as well.
Keep in mind that whatever laptop you buy, make sure you have a cooling pad if you are planning to use FG on it many times/week. Make sure to also monitor the temperature of the CPU and GPU using apps like speedfan because laptops can get 'burned' easily

.
Lastly, do not let the price trick you, if you bought a desktop with more or less the same specs, you'd have to pay about the same price but that won't include a monitor+webcam&mic+portability+speakers+keyboard
