You forgot to mention your screen preference.
Never mind, gamer usually want larger 15.6" or 17.3" screen.
I cannot find laptops that suit your description. This is the best I can find. This laptop costs $100 above your budget @$1000.
Lenovo IdeaPad Y510p (15.6", 1920x1080, Intel i7-4700MQ, Nvidia GT 750M with 2GB GDDR5, 8GB DDR3, 1000 HDD)
Another possibility using AMD crossfire with Richland laptop.
Acer Aspire V5-552G-X414 Dual VGA Cost only $630 and mount 2 VGA: HD8650M and HD8750M in cross fire mode.
(AMD A10-5757M + 6GB Memory)
I don't know how fast it can be, but it looks promising. No one has ever shared it before.
Will you be the first one?
