It\'s rather dissapointing from the reviews so far.
The FX takes up two PCI slots, one for the card itself and the other for the exhaust cooling mechanism they came up with. The card uses over 70W of power compared to the 9700Pro which uses about 54W. Even with the huge cooling mechanism Tom\'s review claims that the vent on the back of the card reached about 60 degrees Celcius, that\'s about 154 degrees for those of us in the US. The fan has also been noted to be rather loud.
I don\'t mind the faults so much but ATI\'s six month old 9700Pro consistently performs only slightly worse than the FX. In some cases it actually performs better. There are no excuses for that.
As it stands I\'d say the FX is only for the hardest of the hardcore.
