will my gpu handle these

[sam002fc]

hello guys i have a old sapphire radeon hd 6570 2gb ddr3 gpu ( which i will sell within 1 year and will buy a r7 260x) so within this perod i have to perform gaming with it
and so for that reason i have overclocked it and after some crashing and blue screen i have gained a stable oc settings which is 785 on engine and 1105 on memory and i have played far cry 3 on high with no aa and received 35 to 50 fps and bf3 on ultra with no aa (40-50 fps0 and blacklist on mid high settings with avg 36 to 56 fps
so is this the max oc settings for that gpu or will i be able to exceed it???
and plz tell me that can i play bf4, cod ghost and thief at custom high settings with no aa with it????
and i was playing these games @ 1366x768 res

Wow that is some good fps with that slow card.I don't think you can overclock anymore unless you increase voltage through Sapphire's Trixx utility.
You should be able to play those games at medium. Also don't get sapphire 260x.There have been lots of black screen problems reported for that card.
