ok i need to know wich CCC is best for dual 4870 512mb cards?? i have 9.9 and am noting a max of 8-9% performance gains over single card, now it is said there is 15-20% to be gained but i have not seen that. I cant help but think its a CCC issue as both cards run great in single mode and one is a powercolor PCS+ that clocks to 850/980 and the other is a HIS and with software voltage mods cloks the same as the pcs+ without will only get 805/955
