CrossfireX with R9 270x seems flawed?

[oozee]

hi guys, i need your expertise on crossfiring my 2 msi r9 270x graphics cards. i have xfire enabled on the latest ccc, however it does not work on most games i think coz the readout in my msi afterburner is that the 2nd gpu is putting out 0% most of the time. i only manage to play watchdogs on medium settings and its still laggy. same story with farcry3 but at ultra settings. putting out around 30fps only. some games like world of tanks i think does not support xfirex and so one of the gpus are off with its fan not spinning... is this normal? or my system is messed up? running on a10 5800k and 8gb 1600ram

I was running 2 260x in crossfire but only one card ran and my motherboard is crossfire compatible. It is just strange like that and it was causing the video card that was running to overheat due to poor airflow.

I was running Intel G3258 with msi g41 pc mate and 3 x 4GB sticks of RAM.

yah, same thing to me... the primary gpu is doing all the work while the 2nd is doing nothing but still reaches 30+ degrees Celsius... its ridiculus... i havent seen any practicality yet just aesthetics... ccc does say its in xfirex mode...
