Unfortunately my 6870 can only squeeze out high + some medium settings with low AA and get 40-60 FPS, but I'm still loving the graphics and some parts have just blown me away. Can't even imagine what playing on a beast rig with 1080p and very high must be like... But just a message for anyone who hasn't played yet and was worried about only being able to play on medium/high...you still won't be disappointed.
