Problems with using dedicated graphics on laptop

[probotzor]

Greetings good people.I know i am new here but i really need some help.
I recently bought asus k53t series laptop with integrated radeon hd 6520g and dedicated radeon hd 7670m graphic cards.
My problem starts there.I installed the chipset drivers provided on dvd which came with laptop and instead of catalyst control center,i got vision control center.Vision control center shows that my integrated graphic is primary while dedicated one is linked adapter.I taught that it should be like that,so i went to switchable graphic options which offers me to chose between power sawing mode(which should be using integrated adapter) and high performance mode (which should be using dedicated).
But when i tested a game i got no difference between those two modes I have been trying to find out for days if i can use only dedicated graphic card because my bios does not offer me that option and vision center offers me to use just integrated or both linked together(which does not give better performance than just integrated) Drivers for both cards are installed since device manager can see them both,but when i run dxdiag or cpuz/gpuz.hwmonitor etc... it detects only the integrated graphic So i am really looking forward for your help and i am hoping you can provide me with a solution to how can i use just dedicated graphic card or what is a proper way of using this cards i have got

Hi probotzor, Welcome to the forums, It's always advisable to download the latest drivers from the manfs website ASUS - Notebooks- ASUS K53TA the supplied DVD is sometimes out of date and does'nt contain the latest drivers , I think catylist control centre as changed name now to vision control centre, update your drivers from Asus website , If that does'nt help you please post back and we will do our best to help

i have k53tk but i already downloaded drivers from that site you posted :/
thing is both of my cards seem to be installed,integrated as a primary and dedicated as a linked one,but i cant seem to put the dedicated card to use even though i checked the high performance profile in vision center :/ i would like to know if i can use only dedicated graphic while gaming so i can compare results

i tried nfs most wanted 2012 and skyrim...in nfs i get same results on both power saving and high performance mode...skyrim detects only my integrated graphics,but amd system monitor shows that my dedicated is being used while playing skyrim...i tried skyrim with all settings on high and it runs smoothly

i dont know if my cards are working correctly or not :/
