I have two AMD Graphics Cards on my system.
I am quite sure that the Radeon HD 7640G works better than Radeon HD 7500M/7600M Series.
I would just like to use only the 7640G and install proprietary driver from AMD site for the same.
A screenshot to about my System Info has also been provided below.
Any suggestions are most welcome.
