could be my ram..its very smooth..but when comes to a big fire fight it has some jams..i checked my proc n ram usage ..proc was 84% while ram was 97%....i try add somemore gbs of ram n see if it fixes the prob..cause come on a fps like cod cnt need up such a high end proc..its nt like its an rts or rpg...like total war,sins of a solar empire,gta etc
