mixed crossfire not able to get working right. first my specs q6600 on rampage formula x48, 4 gigs a-data,cards are 4870 with 4850 and my power supply is a corsair tx 750 please any help or experience with mixed crossfire. main problems is micro stutter in all games or they just didn't work at all.

and my screen res is 720p what type of gain should i see because cod5 waw frames drop by 30fps when i installed the 4850 .
almost forgot tried drives and ccc 8.6 to 8.9 and this is all done in vista x64
