I've run GTAIV with a 10fps display .
The gpu shark shows that both of the cards are loading for 20%-40% ,and the cpu is running so hard!
How to let the graphics only be ran by the graphic cards?

GTA IV is a badly ported console game and requires a fast quad core CPU to run well, there is no shortcut to this.

But I ran it with : AMD Phenom™ II 965X4 ; nvidia 550Ti before,
that was better than : AMD Phenom™ II 965X4(4100MHz) ; EAH6870 CF (overdrived)
The cpu is running as fast as it can!

Check your drivers and also try running the games with crossfire disabled, some games have problems with things like that.

If I remember corectly, most people had to actually disable crossfire in order to get the game to play.

1.04 or 1.4 patch will fix that problem.
change all video option to mid and view distance lower then 40
car 40, shadow 0, lower it most of all option it will let you play smooth

I did try the method above, but the problem is that the graphic cards won't start working until the graphic freeze.0% of loading on two cards.
