hello tom's team,are there any important softwares(optional) ,other than ccc for amd cards,that can be installed for improving game's quality(like colours,textures,eyecandy.),and performance(like framerate) ?
Without getting really involved not really. ATI Tray Tools is something I have used in the past but you would need to have a pretty god understanding of what you are doing and indeed are trying to accomplish to get any improvement over that which you can achieve using CCC alone.
Its not push button stuff, it allows access to higher level settings which the CCC does not.
Afterburner is pretty much the go to over clocking tool as far as improving frame rates are concerned. A third party over clocking tool like this will usually result in a higher over clock than the CCC will. Not always but in my experience its usually better.
