About Your 65`C ; I Think Its Normal , I Got 59`c When I Playing Half-Life 2 at 1600x1200+4xAA and your Card (The GTX Version) Has More Clock and 65`C is Noraml
And Yes It`s True , Your Card is A Monster , And Can Take Everything , You Shold Be Able To Play FEAR at Maximum Settings (except SoftShadows) +at Least 2xAA Fine , Dont Worry , as prozac26 Said , FEAR Will do That . (any Way FEAR is a ATI Game :!: )
