I started a thread about this a few days ago but after some testing I don't think the title of the original thread was accurate so I apologize for making a second thread about it.
I upgraded from dual 3870s to a 4870X2 and I'm getting very subtle snow-like artifacting. It's only really visible on off-white colors and on thin lines (such as the thin red lines used in the design of the [H] front page). At first I though this was limited to 2D as games appeared to play great but I've found I can see the same sparkly snow effect by staring at the overcast sky on cp_granary in TF2.
Some odd things I have found: This is only noticeable on my 30" LG W3000H. I can't see it when hooked up to one of my older 21" displays. It does also not occur with only the basic windows display driver running and no ATI driver installed (I have tried the 8.54s, 8.8, 8.7 and 8.6 hotfix, they all have the snow).
The card's temps are fine, running mid-40s at idle. I am using a 6 to 8-pin adapter for power as my PSU has no 8-pin, but it is a very high quality power supply and I don't see this being an issue.
I guess the question comes down to should I RMA the card or is something else at fault?
