Already when you see the box, we say "wow it's huge!".
But then when you install it in the PC, it gets even more interesting! Associated with an i5 3570k, I run all games Ultra (BF3 / GW2 / other) without any lag.
The menu is very well cooled and honestly I did not hear (can be involved, but since I have the sound I hear any more ^^). In addition, the utility provided with is very simple and quickly lets you toggle between "more performance" + calm "or" cold + ", allowing to manage their card.
Usually full power game it is around 50 degrees, and choosing the "+ cold" you can easily reach the have around 34/37 degrees (off course games).
In short I highly recommend, it is far better than the other 7870 (on the performance / price / consumption) and it still remains below prices in 7950.
