my pc specs:
i5 - 4570 3.20GHz
sapphire 7950 3gb Vapor-x
Gigabyte h87n-wifi
8 gb ram
600 w psu from corsair
h60 water cooler

i constantly have to play BF3 in low settings. if i play on high or medium it lags. and the fps are always low even in low settings like, 20 and below.

About the overclocking softwares.
i cannot overclock, can't change my fan speed, no temperature reading and many more.
i have used both sapphire trixx and msi afterburner. neither seems to work,
HELP ME!
I AM NEW IN THIS FIELD!
