i would like to thank you all for you replies
i tried just now to overclock to 4.6 and i took me some time to get it stable had to disable hyper threading tho but unfortunately the fps didn't change much
then i tried to update chip-set and sata drivers as suggested but it didn't seem to be the problem either
then i downloaded amd driver detector and it detected that my gpu is updated to latest version
my problem isn't a big one i mean i still have many games running perfectly without any whining but the thing is some games which i got the last year or 2 and wanted to finally play on my new pc "didn't work the way i expected"
here is a list of my pc games
witcher2 assassin of kings - works perfect
saints row the third - works perfect
need for speed hot pursuit - works perfect
modern warfare3 - works perfect
battle field 3 - works perfect "slight tearing tho on soldiers/weapons selection screen before deployment in multilayer" but the actual game play is superb
star craft II - works perfect
dungeon siege III- works perfect
on the other hand here is list of games that kept whining
fable3 - works perfectly but when i turn left or right while running or walking i feel a split second fps lag/drop it's slight but it's happening a lot and frame rate stays at 30fps never goes more than that
gta iv - i really don't want to speak about it anymore this is the worst game ever
assassins creed brotherhood - crashed my gpu i don't know how but all of the sudden when i was about to start some quest the screen turned green i didn't wait to see more and clicked the rest button on my case then uninstalled it
and some crappy game called venetica which gave me like 5 fps whenever a cut scene occurs and it stays after to the game play itself "to fix it i had to keep alt tab out and in to the game"
finally world of Warcraft on wotlk i have no problem on raid zone or pvp but the problem is in centeral area "dalaran" with many afk people there sure will be fps drop but i thought my gpu can finally handle it "this is currently on a private server ofc"
and on retail "cataclysm" my character level is still low to test raid or pvp zones like alterac valley
but whenever i buy fly from zone to another i feel fps drop while i'm about to enter a new zone and also when the fly mount decents from a huge mountain an such elevations
this is all the problems i found so far
if i didn't find a fix for it i will just get myself accustomed but really i never intended to troll or anything my problem is a real one
thanks again for all the answers and your advices
