In my experiences, using edge or box makes no difference. Using 8x Adaptive AA is the real killer. It looks awesome, but it can get really 'chuggy'. If you drop it down to 4x in game, it will help your fps a lot. Ran fine for me even on even a 4850 at 4x, and it still looks really good.

Yeah, same thing here... In my experience, G80 and GT200 based cards run WoW the best at 8xAA. I had to drop down to 4x on every G92, RV6xx, and RV7xx card I've tried. It has always been my theory that it was due to the higher memory bandwidth on the G80 cards, but that doesn't really explain the drop in fps with the RV770 cards. Maybe somehow 256-bit GDDR5 doesn't equal 512-bit GDDR3 in some cases. I'm really not sure, but I am familiar with the fps drops you are talking about with the 4870.
