I have been having problems with my 4850 for about a month now. I first realised there was a problem when I hooked up my second monitor to the card. It worked well for around 3 weeks, but then it stopped picking up one of the monitors on bootup (no signal or something) and occasionaly it would find it again. However when both monitors worked together every hour or so both monitors would go completely black for a few seconds. I was on catalyst 8-10 I think, but I put in my old graphics card, an x1900 and it seemed to solve the problems. I put the hd4850 back in a day later and the problems stopped for a while.
The problem is that games don't look right. They seem fuzzy and the textures look awfull even on highest settings. It's as if the anti-aliasing is off even though it isn't. Direcx9 games however look fine like left4dead. I used to play farcry2 on quite high settings without it jerking or looking bad, but now doesn't seem right and lags quite a bit. I have updated catalyst drivers every update and I'm on 8-12 right now. Is it the card thats faulty? If it is I won't be able to return it because it's not completely broken.
