Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I've read in a couple of posts that the 6800U from eVGA should be clocked at 425/1100 from the factory. The card that I got from them is not overclocked, though. It is the standard 400/1100. If you have an eVGA 6800U, please participate in this poll. I want to get to the bottom of this. Thanks.
I have an eVGA 6800U that came clocked at 400/1100. The best I could get out of it is 435/1150. The drivers will let me do 440/1160, but then I get artifacts. Any higher and the drivers reject it. My system consists of an AMD64 3200+, 2 GB of ram, 2 optical drives, 2 hard drives, a sound...
FWIW, I have a 3200+ with a BFG6800NU (16x6, 400/800) and 2 GB of ram and no stuttering. I run at 1680x1050 with mediocre frame rates, but they are consistently mediocre. I have to attribute the non-stuttering to the 2 GB of ram.
