Overall i'm well impressed with my ATi 4870x2 (now that i've changed the fan speed settings) but the one thing that i'm not so impressed about is the drivers for the card.

I installed Crysis Warhead and on gamer settings with full AF I was getting 21fps. :o I updated the drivers to the latest catalyst 8.8 drivers and the fps doubled.  It seems to me that the drivers are awful for the X2 and ATi seriously need to sort them out if they want to keep their lead over Nvidia.
