Your X700 was always running at "full power" because of drivers that do not support this (I assume you was using the r300 driver). And it seems like the fire effect needs some gpu power to be smooth.
This slow effect thing happens on each and every single effect.
The effect gets pretty fast once it has been practised for awhile.
I do understand what you say. Then my question would be how do I do to use all the potential of my card ?
And once again I repeat, I'm not the only one with that problem, this happens to a lot of people.
