What games did you test and what resolution do you play on ?

Crysis 2 gets worse with cross fire. other games should be ok

BTW, nice CPU, I'm jelly

I heard Crysis 2 has absolutely terrible crossfire driver support, so that may be the problem if other games work fine.

i play all my games on 1920x1080
i tested fps with cod 4, bf3 beta, bc2 but i get no difference in any of them according to fraps this is with crossfire turned on and off
any thing you think i should try?
btw thanks for the fast response

Try running unigine heaven 2.5 and see if there is a difference.

Yep try unigine and check if it makes any differences or not.
Also make sure V-sync is disabled
