I have a 550 ti due to cost restraints. Just about any external graphics blow Intel HD Graphics away. The card is pretty nice, but I do not play BF3. Most all FPS I play have been on the PS3, though I am starting to move more to gaming on my PC. The link below will show you how all nvidia/ati/intel graphics compare to each other, what is your budget for a card? The HD6850 does out perform the 550 on paper.
