jazh23I don't known that the gigabyte's fan has a durability problem,

jazh23I'll buy a new card because currently I can't run games smooth with maxim settings like Far cry 3, or Assassin's creed 3, etc.

IkarugaSome of them tend to become a little noisier over time (not all tho), and since you get three of them on a card, it can be an issue later, but it's not a bad card at all, nothing is perfect.

While things will run much smoother indeed, don't expect super-smooth 60+pfs in every single game if you plan to use ultra settings, because you need a stronger setup in 1080p for that. Far Cry 3 needs more than a single card with ultra , but the 670 will max out BF3 in 1080p, no problem.
