so i built my computer last month with a sapphire hd 7970 and an fx 8350 and i started to play bf3 and i hvae noticed that iv gotten low fps or the fps would drop randomly. i would get around 65-75 fps most of the time then it would go down to 60 or even 50 fps when playing the game. ive seen people with the same setup to get around 80+ fps almost always with very little drops fps is there any way something could be causing this and i am running everything on ultra no vsync and motion blur turned off.
