Very good model!!!
As far as performance is concerned, it's on a par with a 7800XT (I've never understood comments like "WoW super powerful, amazing stuff" compared to what? your old card, which is when?).
Otherwise, where the card is good is on the cooling/noise ratio, the card stabilises between 50 and 56c depending on the game (hot spot at 70c + though) all with a very acceptable noise level.
