ati/amd hd 4870 graphics card
windows 7 proffesional
8gb 1600mhz Corsair

Well the 4870 is not a great card to try to play BF3 and to help stabilize your graphics overclock the cpu.

uhhh how much did you pay for the 4870? because i would almost certainly recommend something else...

if im not mistaken, the 4870 only has 512mb of vram. the problem you're running into could be related to running out of vram in certain areas. thats certainly what it sounds like...going from great to terrible very quickly.
