no u don't.
U have 2x 6600GT, the one on his link was a 6600.
And as u know there is a big difference. And no 2x 6600GT can't run FEAR with everything maxed out with eye candies at max and with the highest reso. So not all of the newest games.
But then again, u need a 7800GTX 512 mb to play FEAR with that kind of settings.
