I bought a 6870 about a year ago (I had a 8400gs at the time) and it worked epic. About 6 months later I used it in crossfire and it shuttered on BF3 ultra settings. I don't know why though, I figure it would shutter with 1 GPU cause I'm on 1080p but why did this happen? I sold the 2ng GPU because crossfire did not help me.
Basicly
1 GPU:
high = 40-60 FPS (No AA)
ultra 10-20 FPS
2 GPU:
high = 60-80 FPS (No AA)
ultra 10-20 FPS
