    I am using the pair with an early 2008 Mac Pro octo 2.8. Previous card was a 8800 GT, and previous monitor was a dell 2405WFP. No issue there (other than the 8800's fan noise).

    With the new setup, I occasionally get a whole screen flicker for a split second, and just now when I woke the display from sleep I got multicolored snow covering the entire screen, like this:

    (iphone photo, all I had handy)

    Has anyone seen this with either the EVGA card pushing some other dual-link 30" display, or the 3007wfp-hc driven by some other card? I don't really have an easy way to test this myself, as it is pretty intermittent the two arrived around the same time, so I'm not sure which is the cause, but I haven't seen any problems like that in XP so I'm leaning towards the card (drivers, perhaps). I don't spend much time in XP, though, so I'm still not sure.

    I've seen this happen on my Early '08 Mac Pro with a flashed XFX 4870 as well as the official EVGA GTX285 Mac Edition on my 3007WFP-HC. However, it happens far less frequently with the GTX285 than it did with the flashed 4870.

    From what I have read, it's a pretty common issue.

    I have an '09 Mac Pro and no such issues. Do you have the latest drivers from Nvidia? They were updated just about 1 week ago or so.

    Yes, I have the most recent drivers from nvidia, and to my knowledge there hasn't been any change in frequency of the flickers.
