How do you get the AF to 16 have you changed the xml file? or id it in the Nvidia control panel? The only diff you have in specs to my PC is your cpu and I'd love to get shots like yours without Photoshopping themI modified the chase cam for taking screenshots.
my system:
i7 950 @ 3.07 ghz
6 gb ram
GTX460 2 gb vram
Windows 7 64 Ultimate
1920*1080, AA*16, AF*16
