my current system : i5 2400 intel h61 gtx 670 cooler master 600W psu ocz agility 3 120 gb 500gb hdd
i play battlefield mostly at 1080p monitor but with single 670 i get a lot of fps drops in big maps....i want atleast fps>45....should i grab another 670 or wait for better drivers or change anything in my current system ?
More aboutwhere here
I reccomend a 700w or 750w psu for sli configurations. I am surprised that the 670 wasn't able to achive those framerates. How much ram do you have and what version of windows. 64 bit or 32 bit.
you cant SLI on that motherboard
If you want a second GTX 670 you will have to replace mb , power supply and probably a new copy of windows
Turn AA down a couple of notches and AF down too and see if thats an acceptable compromise
