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: http://picasaweb.google.com/lh/phot...?authkey=Gv1sRgCN7djarmg9CGLg&feat=directlink (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.
