lowest minimum fps for a 6950 is 51 fps.
If its any constoliation, 470 user, and lower, have much lower minimum fps than you.
You could always play at a lower resolution than 2560x + 4xAA + 16AF, if you need more min fps than that.
How do you get 10fps?
Do you play at 7000x2000 resolutions or something sick?
or do you have like a 1ghz cpu or something?
But Nvidia guys have better minimum fps.... probably in some games, but its not by huge amounts.
